  • 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
  • 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
