OCP2183

WWW.ORIENT-CHIP.COM OCP2183 Low-Cost, 3A, 4.5V to 24V Input, 360kHz, PWM Step-Down Synchronous Rectified DC-DC Regulator ◼ General 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. The OCP2183 is idea for distributed power systems, pre-regulation, set-top boxes, television, and other consumer application. The OCP2183 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...
