Overview

PT4301, PT4303 4 Channel 1×/1.
5× Auto-Adjust Charge Pump White LED Driver GENERAL 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 components to construct a LED driver, which makes the PT4301/03 an ideal choice for portable applications.
The LED fault detection circuit in the PT4301/03 improves the reliability of the system.
The PT4301/03 has three dimming modes that allow users to adjust the brightness of the four LEDs individually or all together.
The first t...
