MP3309A Datasheet (MPS) - White LED Driver

MP3309A, White LED Driver

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.
