MP4320 Switching Voltage Regulators

Monolithic Power Systems (MPS) MP4320 Switching Voltage Regulators are 350kHz to 1.8MHz configurable-frequency, synchronous, step-down switching converters with integrated internal high-side and low-side power MOSFETs. These regulators operate at 3.3V to 36V input voltage (V_IN) range and 42V load dump tolerance that meet step-down applications in automotive input environments. The MP4320 regulators provide up to 0.5A of highly efficient output current (I_OUT) with peak current mode control. The open-drain Power Good (PG) signal indicates whether the output is within 94.5% to 105.5% of its nominal voltage. The MP4320 regulators are available in a QFN-12 2mm x 3mm package with wettable flanks. These regulators are ideal for USB chargers, aftermarket automotive applications, battery-powered systems, and general consumer applications.
