MPQ4425C
MPQ4425C is Synchronous Step-Down LED Driver manufactured by Monolithic Power Systems.
DESCRIPTION
The MPQ4425C is a high-frequency, synchronous, rectified, step-down, switch-mode white LED (WLED) driver with integrated internal power MOSFETs. It offers a pact solution that can achieve up to 1.5A of continuous output current (IOUT) across a wide 4V to 36V input voltage (VIN) range, with excellent load and line regulation.
Synchronous mode offers high efficiency across the entire IOUT load range. Current mode control provides fast transient response and improved loop stabilization.
Full protection features include over-current protection (OCP) and thermal shutdown.
The MPQ4425C requires a minimal number of readily available, standard external ponents, and is available in a space-saving QFN-13 (2.5mmx3mm) package.
