TPS92560MR16BSTEVM: 500mA @ 20V, 12V in, Boost

Summary

This user’s guide describes the characteristics, operation and use of the TPS92560MR16BSTEVM evaluation module. This EVM contains Texas Instruments' TPS92560 configured as a boost LED driver solution for MR16 applications. This EVM can deliver up to 12-W output power with a typical 12-VAC (50Hz/60Hz) power source. The EVM is ideal for typical MR16 or AR111 applications that require high compatibility to different power sources. This user's guide includes EVM specifications, recommended test setup, test results, bill of materials, and a schematic diagram.

The TPS92560 is a simple LED driver designed to drive high power LEDs by drawing constant current from the power source. The device is ideal for MR16 and AR111 applications which need good compatibility to DC and AC voltages and electronic transformers. The hysteretic control scheme does not need control loop compensation while providing the benefits of fast transient response and high power factor. The patent pending feedback control method allows the output power to be determined by the number of LED used without component change. The TPS92560 supports both boost and SEPIC configurations for the use of different LED modules.
