MP3309CGQG - White LED Driver

Download the MP3309CGQG datasheet PDF. This datasheet also covers the MP3309C variant, as both devices belong to the same white led driver family and are provided as variant models within a single manufacturer datasheet.

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.

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.

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