STR-A6153E, Universal Input / 20W Flyback Switching Regulator

g n i h tors c t i a Sw egul R STR-A6153E Universal-Input/20 W Flyback Switching Regulator The STR-A6153E is a PRC topology (fixed off-time) regulat.
and applications information is provided in Application Note 28103.

Features

* Rugged 650 V Avalanche-Rated MOSFET Simplified Surge Absorption No VDSS Derating Required
* 1.9 Ω rDS(on)
* Two Operational Modes by Automatic Switching: PRC Mode for Normal Operation Burst Mode for Stand-By Operation or Light Loads
* Built-In Leading Edge Blanking
* Low Start-

Applications

* from DVD and VCR players to ac adapters for cellular phones and digital cameras. An auto-standby function reduces power consumption at light load, while multiple protections, including the avalanche-energy guaranteed MOSFET, provide high reliability of system design. Cycle-by-cycle current limiting
