LTM4686B Ultrathin Dual 14A or Single 28A µModule Regulator
With Digital Power System Management

DESCRIPTION

Demonstration circuit 3089A is a dual-output, high efficiency, high density, µModule regulator with 2.7V to 5.75V input range. Each output can supply 14A maximum load current. The demo board has a LTM4686B µModule regulator, which is a dual 14A or single 28A step-down regulator with digital power system management. Please see LTM4686B data sheet for more detailed information.
DC3089A powers up to default settings and produce power based on configuration resistors without the need for any serial bus communication. This allows easy evaluation of the DC/DC converter. To fully explore the extensive power system management features of the part, download the GUI software LTpowerPlayTM onto your PC and use LTC's I2C/SMBus/PMBus dongle DC1613A to connect to

the board. LTpowerPlay allows the user to reconfigure the part on the fly and store the configuration in EEPROM, view telemetry of voltage, current, temperature and fault status.
GUI Download
The software can be downloaded from: ltpowerplay
For more details and instructions of LTpowerPlay, please refer to LTpowerPlay GUI for LTM4686B Quick Start Guide.

QUICK START PROCEDURE
Demonstration circuit 3089A is easy to set up to evaluate the performance of the LTM4686B. Refer to Figure 2 for the proper measurement equipment setup and follow the procedure below.
1. With power off, connect the input power supply to VIN (2.7V-5.75V*) and GND (input return).
2. Connect the 0.5V output load between VOUT0 and GND (Initial load: no load).
3. Connect the 0.7V output load between VOUT1 and GND (Initial load: no load).
4. Connect the DVMs to the input and outputs. Set default jumper position: JP1: ON; JP2: ON.
5. Turn on the input power supply and check for the proper output voltages. VOUT0 should be 0.5V ±0.5%, and VOUT1 should be 0.7V ±0.5%.

6. Once the proper output voltages are established, adjust the loads within the operating range and observe the output voltage regulation, ripple voltage and other parameters.
7. Connect the dongle and control the output voltages from the GUI. See "LTpowerPlay GUI for the LTM4686B Quick Start Guide" for details.
Note: When measuring the output or input voltage ripple, 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 output capacitor. The probe's ground ring needs to touch the (­) lead and the probe tip needs to touch the (+) lead.

* ­ If 2.70V < VIN <5.50V, R9=OPEN, R91=R92=0ohm
­ If 4.50V < VIN < 5.75V, R9=0ohm, R91=R92=OPEN

LTPOWERPLAY SOFTWARE GUI
LTpowerPlay is a powerful Windows based development environment that supports Linear Technology power system management ICs and Modules, including the LTM4675, LTM4676A, LTM4677, LTM4678, LTM4686, LTC3880, LTC3882 and LTC3883. The software supports a variety of different tasks. You can use LTpowerPlay to evaluate Linear Technology ICs by connecting to a demo board system. LTpowerPlay can also be used in an offline mode (with no hardware present) in order to build a multichip configuration file that can be saved and reloaded at a later time. LTpowerPlay provides unprecedented diagnostic and debug features. It becomes a valuable diagnostic tool during board bring-up to program or tweak the power management scheme in a system, or to diag-

nose power issues when bringing up rails. LTpowerPlay utilizes the DC1613A USB-to-SMBus controller to communicate with one of many potential targets, including the LTM4675, LTM4676A, LTM4677, LTM4686, LTC3880, LTC3882, LTC3883's demo system, or a customer board. The software also provides an automatic update feature to keep the software current with the latest set of device drivers and documentation. The LTpowerPlay software can be downloaded from: ltpowerplay

LTPOWERPLAY QUICK START PROCEDURE
The following procedure describes how to use LTpowerPlay to monitor and change the settings of LTM4686B. 1. Download and install the LTPowerPlay GUI:
ltpowerplay 2. Launch the LTpowerPlay GUI. a. The GUI should automatically identify the DC3089A. The
system tree on the left-hand side should look like this:

Then, click the "W" (PC to RAM) icon to write these register values to the LTM4686B. After finishing this step, you will see the output voltage will change to 0.6V.

b. A green message box shows for a few seconds in the lower left hand corner, confirming that LTM4686B is communicating:

If the write is successful, you will see the following message:

c. In the Toolbar, click the "R" (RAM to PC) icon to read the RAM from the LTM4686B. This reads the configuration from the RAM of LTM4686B and loads it into the GUI.

e. You can save the changes into the NVM. In the tool bar, click "RAM to NVM" button, as following:

d. If you want to change the output voltage to a different value, like 0.6V. In the Config tab, type in 0.6 in the VOUT_COMMAND box, like this:

f. Save the demo board configuration to a (*.proj) file. Click the Save icon and save the file. Name it whatever you want.
