TPS61161ADRVR +BOM

White LED driver with PWM brightness control in 2mm x 2mm WSON Package. up to 10 LEDs in Series

TPS61161ADRVR General Description

By utilizing a pulse width modulation (PWM) signal on the CTRL pin, the LED current in the TPS61161ADRVR can be controlled, with the duty cycle dictating the feedback reference voltage. In PWM dimming mode, the TPS61161ADRVR avoids bursting the LED current, averting any audible noises on the output capacitor. Additionally, the device boasts integrated open LED protection, ensuring that the output does not surpass the absolute maximum ratings in open LED scenarios

Key Features

  • Input Voltage Range: 2.7 V to 18 V
  • 26-V Open LED Protection for TPS61160A
    38-V Open LED Protection for TPS61161A
  • 200mV Reference Voltage With ±2% Accuracy
  • PWM Interface for Brightness Control
  • Built-in Soft Start
  • Up to 90% Efficiency
  • 2-mm × 2-mm × 0.8-mm 6-Pin WSON Package With Thermal Pad
