LED Driver PT4303 1x/1.5x Auto-Adjust Charge Pump 4-Channel White LED Driver with Two Dimming Modes GENERAL DESCRIPTION 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 together or individually. Only a few external ponents (two flying capacitors and two filter capacitors at VIN and VOUT) are needed, which makes the PT4303 ideally suited for mobile applications. The current through the LED can be set by an external resistor. The four LEDs can be turned on and off individually or in a group of two...
