Enhanced, High Voltage and
Efficient Standby Mode,
Power Factor Controller
The NCP1605 is a controller that exhibits nearunity power factor
while operating in fixed frequency, Discontinuous Conduction Mode
(DCM) or in Critical Conduction Mode (CRM).
Housed in a SOIC16 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.
General Features
" NearUnity Power Factor
" Fixed Frequency, Discontinuous Conduction Mode Operation
" Critical Conduction Mode Achievable in Most Stressful Conditions
" Lossless High Voltage Current Source for Startup
" Soft Skipt Cycle for Low Power Standby Mode
