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.
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.
