TPS92510 Datasheet (Texas Instruments) - 1.5-A Constant-Current Buck Converter

TPS92510, 1.5-A Constant-Current Buck Converter

The TPS92510 is a 60-V, 1.5-A peak current-mode step-down converter with an integrated high-side MOSFET.

It is specifically designed for driving highbrightness LEDs with a constant current.

The tighttolerance, 200-mV internal reference voltage reduces power dissipation in the current-sense resistor.
