Onsemi NCP1602 | Demoboard NCP1602GEVB
160‐W, Wide Mains, PFC Stage Driven by the NCP1602 Evaluation Board User's Manual
Overview
| Topology | Power Factor Correction |
| Input voltage | 90-265 V |
| Output 1 | 390 V |
Description
The NCP1602BOOSTGEVB is designed to effectively evaluate the 6-pin PFC controller NCP1602, which is designed to drive PFC boost stages. It is based on an innovative Valley Synchronized Frequency Fold-back (VSFF) method. In this mode, the circuit classically operates in Critical conduction Mode (CrM) when control voltage exceeds a programmable value Vctrl,FF. When Vcontrol is below this preset level Vctrl,FF, the NCP1602 (versions [B] and [D]) linearly decays the frequency down to about 30 kHz until Vcontrol reaches the SKIP mode threshold. VSFF maximizes the efficiency at both nominal and light load. In particular, the stand-by losses are reduced to a minimum. Like in FCCrM controllers, internal circuitry allows near-unity power factor even when the switching frequency is reduced.
