PT4301 Description

PT4301, PT4303 4 Channel 1×/1.5× Auto-Adjust Charge Pump White LED Driver GENERAL .
The PT4301/03 is a 4-channel 1x/1.

PT4301 Features

* z 1×/1.5× auto-adjust charge pump z LED current set by external resistor z Programmable 4-channel LED current up to 20mA with 8 levels control through en/set pin z Individual LED dimming control through PWM signals at 3 (PT4301) or 2 (PT4303) control inputs z LED fault detection z

PT4301 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 two dimming modes can be controlled through the EN/SET pin either by appl
