EVAL-LTM4682-A1Z
LTM4682 Low VOUT Quad 31.25A or Single 125A µModule Regulator
with Digital Power System Management

General Description
The EVAL-LTM4682-A1Z evaluation board features the LTM®4682: the wide input and output voltage range, high efficiency and power density, quad output PolyPhase® DC-to-DC step-down µModule® (micromodule) power regulator with digital power system management (PSM). The EVAL-LTM4682-A1Z evaluation board is configured as a 4-phase four output. A similar evaluation board with a 4-phase single output is also available (EVAL-LTM4682-A2Z).
The EVAL-LTM4682-A1Z evaluation board’s default input voltage range is 4.5V to 16V. However, if VIN is lower than 6V and within 4.5V VIN 5.75V, a minor modification to certain existing on-board components is required. See step 8 (Operation at Low VIN: 4.5V VIN 5.75V) in the Procedure section.
The factory default output voltage VOUT [0:3] is 0.7V at 31.25A maximum load current per channel. Each channel can deliver up to 31.25A maximum load current, but forced airflow and heatsink might also be used to further optimize the output power when all output rails are on and fully loaded. The evaluation board output voltages can be adjusted from 0.7V up to 1.35V. Refer to the LTM4682 data sheet for thermal derating curves and recommended switching frequency when adjusting the output voltage.
Evaluation Board Photo

The factory default switching frequency is preset at 575kHz (typical). The EVAL-LTM4682-A1Z evaluation board comes with a PMBus interface and digital PSM functions. An on-board 12-pin connector is available for the users to connect the dongle DC1613A to the evaluation board, which provides an easy way to communicate and program the part using the LTpowerPlay® software development tool.
The LTpowerPlay software and the I2C/PMBus/SMBus dongle DC1613A allow the users to monitor real-time telemetry of input and output voltages, input, and output current, switching frequency, internal IC die temperatures, external power component temperatures, and fault logs. Programmable parameters include device address, output voltages, control loop compensation, switching frequency, phase interleaving, discontinuous-conduction mode (DCM) or continuous-conduction mode (CCM) of operation, digital soft start, sequencing, and time-based shutdown, fault responses to input and output overvoltage, output overcurrent, IC die and power component over temperatures.
The LTM4682 is available in a thermally enhanced, lowprofile 330-pin (15mm × 22mm × 5.71mm) BGA package. It is recommended to read the LTM4682 data sheet and this user guide prior to using or making any hardware changes to the EVAL-LTM4682-A1Z evaluation board.

Figure 2. Proper Measurement Equipment Setup

1. With power off, connect the input power supply between VIN (TP9) and GND (TP10). Set the input voltage supply to 0V.
2. Connect the first load between VOUT0 (TP23) and GND (TP24), connect the second load between VOUT1 (TP20) and GND (TP21), connect the third load between VOUT2 (TP7) and GND (TP8), connect the fourth load between VOUT3 (TP5) and GND (TP6). Preset all the loads to 0A.
3. Connect the DMM between the input test points: VIN (TP1) and GND (TP11) to monitor the input voltage. Connect DMMs between VOUT0+ (TP16) and VOUT0- (TP17), VOUT1+ (TP18) and VOUT1- (TP19), VOUT2+ (TP12) and VOUT2- (TP14), VOUT3+ (TP13) and VOUT3- (TP15) to monitor the corresponding DC output voltages of Channel 0, Channel 1, Channel 2, and Channel 3. These output voltage test points are Kelvin sensed directly across COUT2 (Channel 0), COUT10 (Channel 1), COUT20 (Channel 2), and COUT29 (Channel 3) to provide an accurate measurement of output voltages. Do not apply load current to any of the above test points to avoid damage to the regulator. Do not connect the scope probe ground leads to VOUT0-, VOUT1-, VOUT2-, and VOUT3-.

4. Prior to powering up the EVAL-LTM4682-A1Z, check the default position of the jumpers and switches in the following positions.

SWR0, SWR1 SWR2, SWR3
RUN0, RUN1 RUN2, RUN3
OFF

P1 RUNP ON

P2 P17
WP_01 WP_23

5. Turn on the power supply at the input. Slowly increasing the input voltage from 0V to 12V (typical). Measure and ensure the input supply voltage is 12V and flip SWR0 (RUN0) and SWR1 (RUN1), SWR2 (RUN2), and SWR3 (RUN3) to the ON position. The output voltages should be 0.7V ±0.5% (typical) for VOUT0, VOUT1, VOUT2, and VOUT3.
6. Once the input and output voltages are properly established, adjust the input voltage between 6V to 14V max and the load current within the operating range of 0A to 31.25A max per channel. Observe the output voltage regulation, output voltage ripples, switching node waveform, load transient response, and other parameters. See Figure 3 for proper output voltage ripple measurement.
To measure the input/output voltage ripples properly, do not use the long ground lead on the oscilloscope probe. See Figure 3 for the proper scope probe technique. Short, stiff leads need to be soldered to the (+) and (-) terminals of an input or output capacitor. The probe’s ground ring needs to touch the (-) lead, and the probe tip needs to touch the (+) lead.
The output voltage ripples of Channel 0, Channel 1, Channel 2, and Channel 3 can also be monitored using on-board BNC terminals. Connect short BNC cables from VOUT0 (J3), VOUT1 (J4), VOUT2 (J5), and VOUT3 (J6) to the inputs of a 4-channel oscilloscope (scope probe ratio 1:1, AC-coupling) to observe output voltage ripples.

Figure 3. Scope Probe Placement for Measuring Output Ripple Voltage

(Option) Operation with VBIAS 7. The VBIAS pin is the 5.5V output of an internal buck regulator that can be enabled or disabled with RUNP. The VBIAS
regulator input is the VIN_VBIAS pin and is powered by VIN. The advantage of using VBIAS is bypassing the internal INTVCC_LDO powered from VIN, turning on the internal switch connected to the 5.5V VBIAS to INTVCC_01 and INTVCC_23 of the part, therefore, reducing the power loss, improving the overall efficiency, and lowering the temperature rise of the part when operating at high VIN and high switching frequency. The VBIAS must exceed 4.8V, and the VIN must be greater than 7V to activate the internal switch connecting VBIAS to INTVCC_01 and INTVCC_23 of the part. In typical applications, it is recommended that VBIAS is enabled.

Operation at Low VIN: 4.5V VIN 5.75V 8. Remove R31 to disconnect VIN_VBIAS from VIN. Remove C25. Set RUNP (P1) to the OFF position. Tie SVIN_01 to
INTVCC_01 by stuffing R142 with a 0 resistor. Tie SVIN_23 to INTVCC_23 by stuffing R143 with a 0 resistor. Make sure VIN is within 4.5V VIN 5.75V. Additional input electrolytic capacitors may be installed between VIN (TP9) and GND (TP10) to prevent VIN from drooping or overshoot to a voltage level that can exceed the specified minimum VIN (4.5V) and maximum VIN (5.75V) during large output load transient.

(Option) On-Board Load Step Circuit
9. The EVAL-LTM4682-A1Z evaluation board provides an on-board load transient circuit to measure VOUT peak-topeak deviation during rising or falling dynamic load transient. The simple load step circuit consists of two paralleled 40V N-channel power MOSFETs in series with two paralleled 10m, 2W, 1% current sense resistors. The MOSFETs are configured as voltage control current source (VCCS) devices; therefore, the output current step and its magnitude are created and controlled by adjusting the amplitude of the applied input voltage step at the gate of the MOSFETs. A function generator provides a voltage pulse between IOSTEP_CLK01 (TP22) and GND (TP2). The input voltage pulse should be set at a pulse width of less than 300µs and a maximum duty cycle of less than 2% to avoid excessive thermal stress on the MOSFET devices. The output current step is measured directly across the current sense resistors and monitored by connecting the BNC cable from IOSTEP_01 (J1) to the oscilloscope’s input (scope probe ratio 1:1, DC-coupling). The equivalent voltage to the current scale is 5mV/1A. The load step current slew rate di/dt can be varied by adjusting the rise time and fall time of the input voltage pulse. The load step circuit of Channel 0 or Channel 1 is connected to VOUT0 by default but can be used for VOUT1 by simply removing the 0 jumper R92 and stuffing it at the position of R93 and vice versa. Only one resistor, R92 or R93, can be stuffed at a time to avoid shorting VOUT0 and VOUT1 together. Repeat step 9 to perform load step transient evaluation for the VOUT1 rail. Similarly, load step transient evaluation of VOUT2 or VOUT3 can be performed using the same method described above. See the Schematics section for more details.

Connecting a PC to the EVAL-LTM4682-A1Z
Use a PC to reconfigure the digital power system management (PSM) features of the LTM4682, such as nominal VOUT, margin set points, overvoltage/undervoltage limits, output current and temperature fault limits, sequencing parameters, the fault logs, fault responses, GPIOs, and other functionality. The DC1613A dongle can be hot-plugged when VIN is present. See Figure 4 for the proper setup of the evaluation board.
