General Description

The MAX5069 is a high-frequency, current-mode, pulse-width modulation (PWM) controller (with dual MOSFET drivers) that integrates all the building blocks necessary for implementing AC-DC or DC-DC fixed-frequency power supplies.

Isolated or nonisolated pushpull and half/full-bridge power supplies are easily constructed using either primary- or secondary-side regulation.

Current-mode control with leading-edge blanking simplifies control-loop design and a programmable internal slope-compensation circuit stabilizes the current loop when operating at duty cycles above 50%.

Overview

19-3175; Rev 1; 7/04 High-Frequency, Current-Mode PWM Controller with Accurate Oscillator and Dual FET.

Key Features

Current-Mode Control with 47µA (typ) Startup Current.
Oscillator Frequency Programmable to 2.5MHz.
Resistor-Programmable ±4.5% Accurate Switching Frequency.
Dual Gate-Drive Output for Half/Full-Bridge or Push-Pull.
