Beschreibung

The IS32PM3420A regulator is a fully integrated and high frequency synchronous step-down DC-DC converter that can drive a load current of up to 3A. It can operate within an input voltage range of 3.8V to 36V. The IS32PM3420A provides exceptional efficiency, output accuracy and drop-out voltage in a very small solution size. Constant on-time control mode isemployed to achieve simple control-loop compensation and fast transient response. Force Continuous Conduction Mode (FCCM) at light loads significantly reduces the output voltage ripple. It requires few external components. Pin arrangement allows simple, optimum PCB layout. Protection features include thermal shutdown, VDD under-voltage lockout, cycleby-cycle current limit, over-voltage and output short circuit protection.
