Description
The NCP1655A is an innovative multimode power factor controller[1]. The circuit naturally transitions from one operation mode (CCM,CrM or DCM) to another depending on the switching period durationso that the efficiency is optimized over the line/load range. In verylight−load conditions, the circuit enters the soft−SKIP mode forminimized losses. Housed in a SO−9 package, the circuit furtherincorporates the features necessary for building robust and compactPFC stages, with few external components.The evaluation board is a 500−W wide−mains PFC stage
Typical applications
- PFC, Wide-Mains
