供应NCP1653A连续导电模式(CCM)PFC功率因素校正电源IC dzsc/18/2270/18227066.jpg Compact, Fixed-Frequency,Continuous ConductionMode PFC ControllerThe NCP1653 is a controller designed for Continuous ConductionMode (CCM) Power Factor Correction (PFC) boost circuits. Itoperates in the follower boost or constant output voltage in 67 or 100kHz fixed switching frequency. Follower boost offers the benefits ofreduction of output voltage and hence reduction in the size and costof the inductor and power switch. Housed in a DIP−8 or SO−8package, the circuit minimizes the number of external componentsand drastically simplifies the CCM PFC implementation. It alsointegrates high safety protection features. The NCP1653 is a driverfor robust and compact PFC stages.Features• IEC1000−3−2 Compliant• Continuous Conduction Mode• Average Current−Mode or Peak Current−Mode Operation• Constant Output Voltage or Follower Boost Operation• Very F...
