Design Example Report (DER-531) from PI uses InnoSwitch-EP 900V rated, the industry's first

AC/DC IC with isolated, safety rated integrated feedback. This new design demonstrates auxiliary

power supply for industrial application with high power density and very high efficiency.

Features:

• Works for 85-484 V AC input
• Integrated line OV protection makes device safe for up to 650 V AC input
• Built-in synchronous rectification for higher efficiency
• Excellent cross-regulation using SR MOSFET instead of diode
• Primary sensed output overvoltage protection (OVP), eliminating the opto-coupler for fault protection
