Enhanced, High Voltage and
Efficient Standby Mode,
Power Factor Controller
The NCP1605 is a controller that exhibits nearâunity power factor
while operating in fixed frequency, Discontinuous Conduction Mode
(DCM) or in Critical Conduction Mode (CRM).
Housed in a SOICâ16 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
⢠NearâUnity 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
⢠Switching Frequency up to 250 kHz
⢠Synchronization Capability
⢠Fast Line / Load Transient Compensation
⢠Valley Turn On
⢠High Drive Capability: â500 mA / +800 mA
⢠Signal to Indicate that the PFC is Ready for Operation
(âpfcOKâ Pin)
⢠VCC range: from 10 V to 20 V
⢠Follower Boost Operation
⢠Two VCC TurnâOn Threshold Options:
15 V for NCP1605 & NCP1605B; 10.5 V for NCP1605A
⢠These Devices are PbâFree, Halogen Free/BFR Free and are RoHS
Compliant
Safety Features
⢠Output Under and Overvoltage Protection
⢠BrownâOut Detection
⢠SoftâStart for Smooth Startup Operation
⢠Overcurrent Limitation
⢠Zero Current Detection Protecting the PFC stage from Inrush
Currents
⢠Thermal Shutdown
⢠Latched Off Capability
Typical Applications
⢠PC Power Supplies
⢠All Off Line Appliances Requiring Power Factor Correction
