MP3309LGQG
DESCRIPTION
The MP3309L 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 200m V feedback voltage and synchronous rectification reduces power loss and reduces PCB space requirements.
The MP3309L features a programmable switching frequency to optimize efficiency. It supports both analog and PWM dimming.
In addition, the MP3309L has LED open protection, cycle-by-cycle current limit protection, thermal shutdown protection.
