NCP1602 fiche technique
NCP1602
Enhanced, High-Efficiency
Power Factor Controller
The 6−pin PFC controller NCP1602 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 Vcontrol 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. Housed in a TSOP6 package, the circuit also incorporates the
features necessary for robust and compact PFC stages, with few
external components.
