PWRTOP201YAI three terminal off-line PWM switching regulator in the Flyback Buck-Boost circuit configuration. Below is a universal input high precision 14 watt application circuit utilizing Power Integrations PWR-TOP204 switching regulator in the flyback buck-boost configuration. Secondary #3 is used to complete the outer voltage feedback loop thus providing a tightly regulated 5V output. Secondary outputs #1 & #2 drive 3 terminal precision regulators and thus produce tightly regulated +12V & +30V outputs. The component values listed are intended for reference purposes only.
