36 V, 1 A synchronous step-down converter in SOT23-6L

Overview

TopologyBuck Converter
Input voltage36 V
Output 15 V / 1 A
IC revision1.0

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.

Features

  • 88% typical efficiency at 600 mA load (VIN = 24 V, VOUT = 5 V)
  • 91% typical efficiency at 600 mA load (VIN = 12 V, VOUT = 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
  • Precision enable
  • Switching frequency dithering
  • Available in SOT23-6L package

Typical applications

  • Major appliances,
  • smart metering, Industrial 12/24V bus conversion
