TPS92512 Datasheet (Texas Instruments)

TPS92512, 2.5A Buck LED Driver

The TPS92512/HV are 2.5A step-down (buck) current regulators with an integrated MOSFET to drive high current LEDs.

Available with 42 V and 60 V (HV) input ranges, these LED drivers operate at a user selected fixed-frequency with peak-current mode control and deliver excellent line and load regulatio
