LT3950 60V 1.5A LED Driver with Internal Log-Scale Dimming

DESCRIPTION
Demonstration circuit 2788A is a boost LED driver featuring the LT®3950. This demonstration circuit powers a string of LEDs at 330mA. The step-up topology can be used to drive a string of up to 28V of LEDs as assembled. The maximum output voltage capability of the LT3950 is 60V. DC2788A runs from an input voltage range of 6V to 24V as built. It also runs at 2MHz and has the capability to turn on spread spectrum frequency modulation (SSFM) for a frequency range of 2.0MHz to 2.5MHz. Dimming control can be achieved with analog dimming or PWM dimming--either from an external or internally-generated clock source. DC2788A features undervoltage lockout (UVLO) set at 6.6V with a 1.0V hysteresis for turn-on.
The UVLO voltage, LED current, output voltage range, switching frequency, brightness control, SSFM, and the topology can all be adjusted with simple modifications to the demonstration circuit.
LT3950 is a monolithic 1.5A peak switch current, 60V LED driver. The guaranteed peak switch current rating of the IC is 1.5A and this is important to know when calculating maximum output current at a given LED voltage and input voltage for a boost converter. The LT3950 features SSFM and a well-controlled SW node for low emissions.

A frequency range of 200kHz to 2MHz and a high-side PWMTG PWM-dimming MOSFET makes this a very versatile IC for many applications. It can be used for boost, buck-boost mode and buck mode LED driver applications. The PWMTG MOSFET not only provides high PWM dimming ratio capability, but it also serves as a short-circuit protection device. The FAULT flag indicates when there is either a short-circuit or open-LED fault at the output.
The demo circuit is designed to be easily reconfigured to suit other applications, including the example schematics in the data sheet. Consult technical support for assistance.
High voltage operation, 3V input voltage operation, multiple topologies, small-and-compact size, fault protection, low EMI, and multiple brightness control options make the LT3950 flexible and powerful for compact, noise-sensitive LED driver solutions. The LT3950JMSE featured on this demo circuit is available in a thermally enhanced 16-lead plastic MSOP package. The LT3950 data sheet must be read in conjunction with this demo manual to properly use or modify demo circuit DC2788A.

DEMO MANUAL DC2788A

QUICK START PROCEDURE
The DC2788A is easy to set up to evaluate the performance of the LT3950JMSE. Refer to Figure 1 for proper measurement equipment setup and follow the procedure below.
Note: Make sure that the voltage applied to VIN does not exceed 45V, which is close to the maximum voltage rating for the input capacitors.
1. Set JP1 to On and JP2 to GND to disable Internal PWM Dimming and to run the LED driver at 100% duty cycle. Set JP3 to No SSFM to disable SSFM and run at 2.0MHz constant frequency. JP3 can be switched to SSFM On to evaluate the performance of the PCB with spread spectrum frequency modulation.
2. Connect the EN terminal to GND with a clip-on lead. Connect the power supply (with power off), LED load, and meters as shown.

3. After all connections are made, turn on the input power and verify that the input voltage is between 8V and 18V.
4. Remove the clip-on lead from EN. Verify that the LED current is 330mA, the VOUT voltage is between 7.5V and 28V and the FAULT terminal is not asserted low.
Note: If the output voltage is low or if the FAULT terminal is asserted low, temporarily disconnect the load to make sure that the LED string is connected properly and not faulted.
5. Once the proper output current and voltage are established, adjust the input voltage and load within the operating ranges and observe the output voltage regulation, dimming and PWM.

QUICK START PROCEDURE
PWM DIMMING
To evaluate internally generated PWM dimming performance, (with power off) set JP2 = INTVCC and JP1 to INT. PWM dimming duty cycle is set by adjusting the position of VR1 potentiometer with a small screwdriver (with power on). It is safest to switch jumper positions with the power off, and then turn power back on when positions are set.
To evaluate externally generated PWM dimming performance, (with power off) set JP2 = GND and JP1 to EXT. Place a 3.3V or 5V variable duty-cycle input on the PWM terminal to control PWM dimming. PWM dimming frequency should be greater than or equal to 100Hz. 120Hz is recommended for the highest dimming ratio performance without low risk of visible flicker.
ANALOG DIMMING
Constant LED current is controlled by setting the voltage of the CTRL pin on the LT3950. Either a voltage source can be placed on the CTRL turret and set between 200mV and 1.5V for LED current control, or the resistors R16 and R4 can be used to set the CTRL pin voltage with a divider from INTVCC as shown in the schematic. Analog dimming and PWM dimming can be combined for a very high dimming ratio.
EMI FILTERS
EMI input filters are placed on the PCB for low EMI testing results. This PCB passes CISPR25 class 5 conducted and radiated emissions testing for automotive vehicles. The input filter FB1 and C14 helps with high frequency noise at the input. FB2 and C21 help with high frequency noise at the output. Since this converter runs at 2MHz, large AM band (530kHz to 1.8MHz) emissions filters are not needed and the overall solution size is small. EMI filters may not be necessary in all applications, however. For the highest dimming ratio and for the highest efficiency, the input and output EMI filters can be removed.
In order to remove the EMI filters, the ferrite beads (FB1 and FB2) can be shorted out, and the capacitors (C14 and C21) should be removed. Figure 2 through Figure 6 demonstrate the difference in efficiency and

PWM dimming with the EMI filters in place or removed. Extremely high PWM dimming performance is possible without EMI filters, but even with the filters, very high PWM dimming is capable with the LT3950.
ADJUSTMENTS
Other adjustments can easily be made to the demonstration circuit. The overvoltage protection voltage (OVP) can be set by changing the values of R7 and R8. Please read the data sheet for details. R7 and R8 are used to set the VOUT fault voltage when LEDs are removed from the output, but the running LED string voltage should remain below this point to not cause a fault.
The switching frequency can be changed over a wide range by setting the RT resistor, R5. SSFM spreads up from the RT resistor setting to fSW (RT) + 25%. SSFM is turned on and off by changing the jumper position on the PCB. It is that simple. SSFM can be turned on and off for evaluation and emissions testing.
LED current is set with R1 and the CTRL voltage as shown in the data sheet. For the highest accuracy, use CTRL = 1.5V or higher for full-scale LED sense voltage of 250mV. Since the peak switch current rating of the LT3950 is 1.5A, theoretically, about 1A is the maximum current that can be extracted at the output for any topology (buck mode). With very, very small ripple current, 1.2A might be able to be delivered at the output of a buck mode converter, but this might not be very practical. In a boost converter topology, please note that the peak switch current is the input current of the converter plus some ripple. In a boost, the input current can be significantly higher than the LED current. Please do not expect 1.5A LED current in a boost converter with this IC. Much higher peak switch current rating is needed for that.
The converter topology can be changed from boost to buck-boost mode (LEDs returned to VIN) or buck mode. Please consult the factory applications engineers or the data sheet for details. Components Q1, R19, and R20 are used for overvoltage protection in both buck-boost mode and buck mode. They are not used for the boost topology.
