TPS61042EVM-226 White Light LED Bias Supply EVM

This TPS61042EVM uses the TPS61042 boost converter to provide 20 mA of bias current to a four-element white LED from a 1.8 V to 6 V input. This EVM may be modified to drive more or less than four LEDs. It may also be modified to deliver a higher or lower output current to the LEDs. Refer to the data sheet for more information on adjusting the rated output current. The EVM includes a CTRL pin and an ADJ pin that allows the user to dim the LEDs. The LEDs may be dimmed using either an analog or a PWM dimming scheme. Information about output voltage and current ratings of TPS61042 can be found in the data sheet SLVS439.
