MP4323 Synchronous Step-Down Converters

Monolithic Power Systems (MPS) MP4323 Synchronous Step-Down Converters are frequency-configurable (350kHz to 2.5MHz), synchronous, step-down switching converters with integrated internal high-side and low-side power MOSFETs (HS-FET and LS-FET, respectively). The MP4323 delivers up to 3A of highly efficient output current (IOUT) with peak current control mode. The MP4323 offers a 3.3V to 36V wide input voltage (VIN) range and 42V load dump tolerance to adapt to various step-down applications in automotive input environments. The 1μA shutdown current (ISD) enables the device to be used in battery-powered applications.
