PT4305 1x/1.5x Auto-Adjust Charge Pump One Channel White LED Driver for Flash GENERAL DESCRIPTION FEATURES PT4305 is a 1x/1.5x auto-adjust charge pump white z 1x/1.5x auto-adjust charge pump LED driver with maximum 350mA load. Auto-adjust z 350mA maximum load current charge pump achieves high efficiency for Li-Ion battery z <10% feedback voltage reference error Micro Bridge Technology Co.,Ltd. supply. Few external components (two flying capacitors, two filter capacitors at VIN and VOUT, and one feedback resistor) make PT4305 ideally suited for mobility application. The current through the LED can be pre-set by feedback resistor. And the LED can also be dimmed by PWM control signal. Built-in soft-start circuit prevents the inrush current from supply source during power on and 1x/1.
