Description
The TPS61500 is an inductive boost white LED driver with a 3V to 18V input voltage range. The boost has an integrated 130-mΩ 40-V switch with a 3-A (minimum) current limit. The LED current is regulated by controlling the feedback voltage across an external low side currentsetting resistor. Dimming control is provided through the PWM input which is fed into a low-pass filter and made to adjust
