The NCP1605 is a controller that exhibits near unity power factor while operating in fixed frequency, Discontinuous Conduction Mode or in Critical Conduction Mode.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. The NCP1605A version lowers the UVLO ON threshold level to 10.5 V to allow operation with a lower Vcc.
Features   Benefits
     
  • High Voltage Startup Current Source
 
  • Clean & lossless start-up sequence Less components
  • Fixed Frequency, Discontinous Conduction Mode (DCM) or Critical
 
  • The best of the 2 modes: DCM to limit the maximum switching frequency and CRM to lower maximum current stress
  • Soft-Skip during Standby Mode
 
  • Further reduced losses
  • PFC ready signal
 
  • Suitable for topologies requiring limited input voltage range
  • Fast Line / Load Transient Compensation
   
  • Valley Turn on
   
  • Output Under and Over Voltage Protection
   
  • Brown-Out Detection
   
  • Soft-Start for Smooth Start-up Operation
   
  • Over Current Limitation
   
  • Latched Off Capability
   
Applications   End Products
  • Power Factor Correction
 
  • High power AC Adapters
  • Flat TVs
  • Desktop PCs
  • Industrial Power Supplies
