Overview
PT4302 2 Channel 1×/1.
5× Auto-Adjust Charge Pump White LED Driver GENERAL DESCRIPTION The PT4302 is a 2-channel 1×/1.
5× auto-adjust charge pump white LED driver with LED fault detection.
The auto-adjust charge pump achieves high efficiency for an Li-lion battery supply.
LED fault detection feature allows the PT4302 to be self-adjusted to normal operation if an open or short occurs.
The PT4302 needs few external components, which makes it an ideal choice for portable applications where a smaller board space is critical.
The LED current is programmable from 3mA to 25mA in a 3mA step by applying digital codes at the EN/SET pin.
A built-in soft-start circuit prevents a high inrush current from being drawn from the supply source during power on and 1×/1.
5× mode switching.
The thermal shutdown and current limiter prevents the PT4302 from being damaged by short to ground or overload conditions.
The ultra small shut-down current of less than 1µA significantly prolongs the battery life.
