NCP1618 Power Factor Controllers
onsemi's power factor controller transitions to multiple modes depending on the switching period duration
onsemi's NCP1618 is an innovative high-voltage multimode power factor controller. The circuit naturally transitions from critical conduction mode (CRM) to continuous conduction mode (CCM) operation mode and vice versa depending on the switching period duration to keep the efficiency optimized over the line/load range. In very-light-load conditions, the circuit can enter the Soft-Skip mode for minimized losses. The circuit further incorporates the features necessary for robust and compact PFC stages, with few external components being housed in an SO-9 package.
- Multimode operation (CRM-CCM)
- Frequency foldback/Soft-Skip mode
- pfcOK signal
- Jittering in CCM
- Complete protection features: OCP, OVP, BO, BUV, and inrush detect
- Integrated EMI filter capacitor (X2) discharge circuitry
- All offline appliances requiring power factor correction
