MAX5069
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.
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 Applications
- Rectified 85VAC to 265VAC, or 36VDC to 72VDC Input (MAX5069A/B)
- Input Directly Driven from 10.8V to 24V (MAX5069C/D)
- Programmable Dead Time and Slope Compensation
- Programmable Startup Voltage (UVLO)
- Programmable UVLO Hysteresis (MAX5069B/C)
- Frequency Synchronization Input (MAX5069A/D)
