U-169 A Complete Control Solution for a Four-Quadrant Flyback Converter

The UCC3750 Source-Ringer Controller provides a complete control and drive solution for a four quadrant flyback-based ring generator circuit. The IC controls a primary-side switch which is modulated when power transfer is taking place from input to output. It also controls two secondary switches which act as synchronous rectifier switches during positive power flow. These switches are pulse-widt
