Overview
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 protecti...
