TPS92510EVM-011: 740mA @ 38.4V Max, 43 ~ 53V in

Summary

The TPS92510EVM-011 evaluation module (EVM) helps designers evaluate the operation and performance of the TPS92510 DC/DC converter, a high-brightness light emitting diode (LED) driver. The converter is a wide input voltage (3.5 V to 60 V), 2.5-MHz, non-synchronous, externally compensated, step down converter capable of 1.5 A of output current.

The TPS92510EVM-011 provides a high-brightness LED driver based on the TPS92510. The EVM is designed to operate from a nominal 48 VDC ±10% input voltage source. This input voltage range is typical for input supplies derived from AC/DC sources The EVM provides an output current of 740 mA with an output voltage sufficient to drive four to ten off-board LEDs.

This converter design describes an application of the TPS92510 as an LED driver with the specification below. For applications with a different input voltage range or different numbers of LEDs, refer to the application report, How to Design an LED Driver Using the TPS92510 (TI Literature Number SLUA628).
