MPQ4347 Datasheet (MPS) - Synchronous Step-Down Converter

MPQ4347, Synchronous Step-Down Converter

The MPQ4347/4347J is a configurablefrequency (350kHz to 2.5MHz), synchronous, step-down switching regulator with an integrated internal high-side and low-side MOSFET (HSFET and LS-FET, respectively).

The device provides 4A of highly efficient output current (IOUT) with fixed-frequency, zero-delay pu
