Enhanced, High Voltage and

Efficient Standby Mode,

Power Factor Controller

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).

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.

General Features

• Near−Unity 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: −500 mA / +800 mA

• Signal to Indicate that the PFC is Ready for Operation

(“pfcOK” Pin)

• VCC range: from 10 V to 20 V

• Follower Boost Operation

• Two VCC Turn−On Threshold Options:

15 V for NCP1605 & NCP1605B; 10.5 V for NCP1605A

• These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS

Compliant

Safety Features

• Output Under and Overvoltage Protection

• Brown−Out Detection

• Soft−Start 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
