Product Introduction

The PMC1302A is a high efficiency synchronous monolithic step-down switching regulator with integrated internal high-side and low-side MOSFETs. It provides up to 1.5A output current with peak current mode control for fast loop response. The PMC1302A operates over a wide input voltage range from 3.0V to 36V with only 30μA low quiescent current.


Standard features include thermal shutdown, UVLO, enable (EN) control and power good (PG) indicator. During the overload or output short circuit, the cycle by cycle current limit and hiccup protection are provided. Thermal shutdown provides reliable and fault-tolerant operation.
