Our secondary-side regulation PWM controllers and switchers include Flyback power topology with improvements to meet target applications. Crucial features include various PWM operation modes (DCM: Discontinues Conduction Mode, QR: Quasi-Resonant), Continuous Conduction Mode (CCM), QR+CCM, Active Clamp Flyback (ACF), high-voltage start-up circuitry integration, low standby power (<30m Watt, 5V standby output), peak load, and wide output range support for Quick Chargers (3.3V~21V for PD3.0 PPS).
