Product overview

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.

All features
88% typical efficiency at 600 mA load (V_IN = 24 V, V_OUT = 5 V)

91% typical efficiency at 600 mA load (V_IN = 12 V, V_OUT = 5 V)

3.3 V to 36 V input operating voltage range

Up to 1 A output current capability

110 μA input quiescent current

1 MHz fixed switching frequency

Synchronous rectification

Internal compensation network
Peak current mode control

Two different versions: LCM for high efficiency at light loads and LNM for noise-sensitive applications

Output overvoltage protection

Thermal shutdown
