描述 Description

The DCP3601 is a wide-input voltage, easy-to-use synchronous buck converter capable of driving up to 1 A load current. The extended input range from 3.3 V to 36?V makes the device suitable for a wide range of industrial applications.

The DCP3601 operates at 1 MHz fixed switching frequency allowing the use of small inductors for an optimized solution size.

Optional switching frequency dithering is implemented to improve EMI performances.

It is based on a peak current mode architecture, including soft-start circuit, overcurrent protection circuit, overtemperature protection and output overvoltage protection, and is packaged in a SOT23-6L package.
