RDR-321 - 17 W Dual Output Flyback Converter

Overview

Feature Overview • Primary-side regulated, isolated flyback converter with ±5% adjustment accuracy • 132 kHz switching frequency reduces transformer and output filter size. • Full-load continuous conduction mode operation improves efficiency and reduces output capacitor ripple current • Multi-mode operation improves efficiency over the entire load range • Input power is less than 100 mW at 230 VAC, with load standby power dissipation of 50 mW • Adopts comprehensive protection functions, including over-voltage protection (OVP), over-temperature protection (OTP), voltage ramp-up/sag protection, input over-voltage shutdown protection, and loss-of-regulation protection (auto-restart) • Meets EN-550022 and CISPR -22 Class B conducted EMI requirements • Meets the 1 kV/2 kV surge voltage requirements of IEC61000-4-5
