MP3309C Datasheet (MPS) - White LED Driver

MP3309C, White LED Driver

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 mod

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. The I2C interface can set the protecti
