Monolithic Power Systems MPQ4425C
The MPQ4425C is a high-frequency, synchronous, rectified, step-down, switch-mode white LED (WLED) driver with integrated internal power MOSFETs. It offers a compact 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. The MPQ4425C requires a minimal number of readily available, standard external components, and is available in a space-saving QFN-13 (2.5mmx3mm) package.DESCRIPTION
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. MPQ4425C 36V, 1.5A, 2.2MHz, High-Efficiency, Synchronous Step-Down LED Driver, AEC-Q100 QualifiedFEATURES
