PT4301 Description
The PT4301/03 is a 4-channel 1x/1.5x auto-adjust charge pump white LED driver that achieves high efficiency for Li-Ion battery supply. The LED current can be set by an external resistor. Only one small resistor and four 1µF small ceramic capacitors are needed as external ponents to construct a LED driver, which makes the PT4301/03 an ideal choice for portable applications.
