TPS61042 Datasheet (Texas Instruments) - Constant Current LED Driver

TPS61042, Constant Current LED Driver

The TPS61042 is a high frequency boost converter with constant current output that drives white LEDs or similar.

The LED current is set with the external sense resistor (RS) and is directly regulated by the feedback pin (FB) that regulates the voltage across the sense resistor RS to 252 mV (typ).
