1x/1.5x Auto-Adjust Charge Pump 4-Channel White LED Driver With Two Dimming Modes

The PT4303 is a 4-channel 1x/1.5x auto-adjust Charge Pump White LED Driver with two dimming modes. Auto-adjust Charge Pump achieves high efficiency for Li-Ion battery supply. The two LED dimming modes enable users to dim the four LEDs all together or individually. Only a few external components (two flying capacitors and two Filter capacitors at VIN and VOUT) are needed, which makes the PT4303 ideally suited for mobile applications.
