Onsemi NCP1654 | Demoboard DN05067/D
Power Factor Correction Controller for Compact and Robust, Continuous Conduction Mode Pre-Converters
Overview
| Topology | Boost Converter |
| Input voltage | 90-265 V |
| Output 1 | 12 V / 20 A |
| IC revision | 1 |
Description
The NCP1654 is a controller for Continuous Conduction Mode (CCM) Power Factor Correction Step up preconverters. It controls the power switch conduction time (PWM) in fixed frequency mode and is dependant on the instantaneous coil current. Housed in a SO-8 package the circuit minimizes the number of external components and drastically simplifies the PFC implementation. It also integrates high safety features that make the NCP1654 a driver for robust and compact PFC stages like an effective input power runaway clamping circuit.
Features
- Very Few External Components
- Programmable Overcurrent Protection
- BrownOut Detection
- Overvoltage Protection
- Soft Start
- Continuous Conduction Mode
- Average Current-Mode or Peak Current-Mode Operation
- Programmable Overpower Limitation
- Undervoltage Detection for Open Loop Detection (shutdown)
- Inrush Currents Detection
Typical applications
- Power Factor Correction Stage
