OCP2183 - PWM Step-Down Synchronous Rectified DC-DC Regulator

This page provides the datasheet information for the OCP2183, a member of the OCP2183-ORIENT PWM Step-Down Synchronous Rectified DC-DC Regulator family.

Datasheet Summary

Description

The OCP2183 is a low-cost, synchronous DC-DC converter with internal switches delivers an output current up to 3A.

The OCP2183 operates from an input voltage of 4.5V to 24V and provides an adjustable output voltage from 0.920V to 20V, set with two external resistors.

Features

  • a peak-current-mode PWM controller with internally fixed 390kHz switching frequency and a 90% maximum duty cycle. The current-mode control architecture simplifies compensation design, and ensures a cycle-by-cycle current limit and fast response to line and load transients. This synchronous buck regulator features internal MOSFETs that provide better efficiency than asynchronous solutions, while simplifying the design relative to disc.
