Product Summary

The TPS61150ADRCR is a high frequency boost converter with two regulated current outputs for driving WLEDs. Each current output can be individually programmed through external resistors. There is dedicated selection pin for each output, so the two outputs can be turned on separately or simultaneously. The output current can be reduced by a pulse width modulation (PWM) signal on the select pins or an analog voltage on the ISET pin, resulting in PWM dimming of the WLEDs. The TPS61150ADRCR runs at 1.2 MHz fixed switching frequency to reduce output ripple and avoid audible noises associated with PFM control. The applications of the TPS61150ADRCR include Sub and Main Display Backlight in Clam Shell Phones, Display and Keypad Backlight, Up to 14 WLED Driver.
