STMicroelectronics L6566BH
The L6566BH is an extremely versatile current-mode primary controller IC, specifically designed for high-performance offline flyback converters running off rectified 3-phase input lines. It is also suited to single-stage, single-switch, input-current-shaping converters (single-stage PFC) for applications that must comply with EN61000-3-2 or JEITA-MITI regulations. Both fixed-frequency (FF) and quasi-resonant (QR) operation are supported.- Min Voltage : 10.6V
- Max Voltage : 23V
- Channels : 1
- Max Operating Temp : 150°C
- Min Operating Temp : -40°C
