MP3309 Datasheet PDF (White LED Driver)

MP3309 - White LED Driver

Description

The MP3309 is a WLED step-up converter for 2.7V to 5.5V input that uses peak-current mode to regulate the LED current sensed through an external, low-side resistor.

The 200mV feedback voltage and synchronous rectification reduces power loss and reduces PCB space requirements.

Features

a programmable switching frequency to optimize efficiency. It supports both analog and PWM dimming. In addition, the MP3309 has LED open protection, cycle-by-cycle current limit protection, Under voltage protection and thermal shutdown protection .
