LED Driver IC datasheet and documents for MP3305DD-LF-P

MP3305DD-LF-P

LED Driver IC Overview

The MP3305DD-LF-P is a monolithic LED lighting driver IC designed for white LED (WLED) backlight applications. It utilizes a constant-frequency peak-current-mode boost topology with an integrated 0.4Ω power MOSFET and a 0.8Ω LED switch. The device supports a maximum output voltage of 36V and delivers up to 1.3A output current. Operating within a supply voltage range of 2.5V to 6V, it functions at a switching frequency of 2.2MHz. The component features PWM dimming control and overvoltage protection, housed in an 8-pin QFN package.
