MP3309AGQ Datasheet | Monolithic Power Systems

The Future of Analog IC Technology MP3309A 2.7V-5.5V Input, 35V Output, Programmable Fsw, White LED Driver DESCRIPTION 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 acplishes 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,...
