PT4303 driver equivalent, 1x/1.5x auto-adjust charge pump 4-channel white led driver.
* 3V-5.5V input voltage
* 1x/1.5x auto-adjust charge pump
* Set LED current by external resistor
* Dimming LED by PWM signal through 2 control terminal
The current through the LED can be set by an external resistor. The four LEDs can be turned on and off individually or .
The PT4303 is a 4-channel 1x/1.5x auto-adjust charge pump white LED driver with three dimming modes. Auto-adjust charge pump achieves high efficiency for Li-Ion battery supply. The three LED dimming modes enable users to dim the four LEDs all togethe.
