EV3309A-Q-00A Evaluation Kit 2.7V - 5.5V Input, 35V Output, Programmable Fsw, White LED Driver With 12C Interface Evaluation Board
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. To connect an external Schottky accomplishes the non-synchronous mode for heavy load to improve the thermal performance.
The MP3309A features a programmable switching frequency to optimize efficiency. It supports both analog and PWM dimming.
In addition, the MP3309A has LED open protection, cycle-by-cycle current limit protection and thermal shutdown protection. The I2C interface can set the over-voltage protection threshold, analog dimming and read IC status. MP3309A is available in QFN10 3*3mm package.
