MP3309AGQ - White LED Driver

Download the MP3309AGQ datasheet PDF. This datasheet also covers the MP3309A 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 MP3309A 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 MP3309A has LED open protection, cycle-by-cycle current limit protection, thermal shutdown protection and over-voltage protection. MP3309A is available in QFN10 3.
  • 3mm package.

The Future of Analog IC Technology MP3309A 2.7V-5.5V Input, 35V Output, Programmable Fsw, White LED Driver DESCRIPTION The MP3309A 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. To connect an external Schottky accomplishes the non-synchronous mode for heavy load to improve the thermal performance. The MP3309A features a programmable switching frequency to optimize efficiency. It supports both analog and PWM dimming. In addition, the MP3309A has LED open protection, cycle-by-cycle current limit protection, thermal shutdown protection and over-voltage protection.
