The Power Integrations InnoSwitch-CH series of off-line CV/CC flyback switching AC-DC converters incorporates an integrated high-voltage MOSFET with synchronous rectification feedback and many advanced protection and safety features. These devices dramatically simplify the development and manufacture of low-voltage, high current switching power supplies, especially those with high efficiency requirements. The revolutionary InnoSwitch-EP architecture integrates both primary and secondary controllers plus sensing elements and a safety-rated feedback mechanism into a single compact IC.

• Incorporates flyback controller, high-voltage MOSFET, secondary-side sensing and synchronous rectification driver in a single package
• Exceptional CV/CC accuracy, independent of transformer design or external components
• Energy efficient: <10 mW no-load at 230 VAC when supplied by transformer bias winding
• Easily meets all global energy efficiency regulations
• Primary sensed output OVP
• Secondary sensed output overshoot clamp
• Secondary sensed output OCP to zero output voltage
• Hysteretic thermal shutdown
• 100% production HIPOT compliance testing
• Reinforced insulation
• Isolation voltage >3,500 VAC
• EN61000-4-8 (100 A/m) and EN61000-4-9 (1000 A/m) compliant
