LED Driver PT4301 1x/1.5x Auto-Adjust Charge Pump 4-Channel White LED Driver With 3Dimming Modes GENERAL DESCRIPTION The PT4301 is a 4-channel 1x/1.5x auto-adjust charge pump white LED driver with three dimming modes. Auto-adjust charge pump achieve high efficiency for Li-Ion battery supply. Three LED dimming modes enable user to dimming 1 to 4 LED all together or separately. Few external ponent (two flying capacitors, and two filter capacitors at VIN and VOUT) make the PT4301 ideally suited for mobility application. The current through the LED can be pre-set by external resistor. And the current can also be regulated from 3mA to 25mA in 3mA step by the EN/SET pin, which is a digital...
