IS32PM3427 3.8V TO 36V, 4A, 2.2MHZ, SYNCHRONOUS STEP-DOWN VOLTAGE REGULATOR Preliminary Information May 2024 GENERAL DESCRIPTION The IS32PM3427 regulator is an easy-to-use synchronous step-down DC-DC converter capable of driving up to 4A of load current from an input voltage ranging of 3.8V to 36V. The IS32PM3427 provides exceptional efficiency, output accuracy and drop-out voltage in a very small solution size. Constant on-time control mode is employed to achieve simple controlloop compensation and fast transient response. The IS32PM3427 supports both Forced Continuous Conduction Mode (FCCM) and Pulse Frequency Modulation mode (PFM) at light-load condition, which is selected by the FPWM pin. It requires few external components. Pin arrangement allows simple, optimum PCB layout.
