MP3309CGQG Datasheet White Led Driver

Manufacturer: Monolithic Power Systems

Overview: MP3309C 2.7V-5.5V Input, 38V Output, FSW Programmable, White LED Driver with I2C.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The MP3309C 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.

For non-synchronous mode, setting an internal register can disable the rectifier MOSFET to save driver losses.

Key Features

  • a programmable switching frequency to optimize efficiency. It supports both analog and PWM dimming. In addition, the MP3309C has LED open protection, cycle-by-cycle current limit protection, thermal shutdown protection, and VOUT to GND short-circuit protection. The I2C interface can set the protection indication bits and over-voltage protection point.
