CD5021 Overview
Description
The CD5021 off-line pulse width modulation (PWM) controller contains all of the features needed to implement highly efficient off-line single-ended flyback and forward power converters using current-mode control. The CD5021 features include an ultra-low start-up current, which minimizes power losses in the high voltage start-up network.
Key Features
- Ultra-low Startup Current
- Current Mode Control
- Skip Cycle Mode for Low Standby Power
- Single Resistor Programmable Oscillator
- Synchronizable Oscillator
