TPS61043 Datasheet - Texas Instruments

TPS61043 Constant Current LED Driver

The TPS61043 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 (typical).

TPS61043 Features

* 1 Current Source With 18-V Overvoltage Protection

* Powers up to 4 LEDs in Series

* Input Voltage Range: 1.8 V to 6 V

* Internal 30-V Switch

* Up to 85% Efficiency

* Precise Brightness Control Using PWM Signal or Analog Signal

* Switching Freq
