MARKING

The NCP1605 is a controller that exhibits near−unity power factor

while operating in fixed frequency, Discontinuous Conduction Mode

(DCM) or in Critical Conduction Mode (CRM).

DIAGRAMS

Housed in a SOIC−16 package, the circuit incorporates all the

features necessary for building robust and compact PFC stages, with

a minimum of external components. In addition, it integrates the skip

cycle capability to lower the standby losses to a minimum.
