Controller
The NCP1601isa controller designedfor Power Factor Correction
(PFC) boost circuits. The device operatesin fixed- -frequency
Discontinuous Conduction Mode (DCM) and variable- -frequency
Critical Conduction Mode (CRM) and takes advantages from both
operating modes. DCM limits the maximum switching frequency.It
simplifies the front- -ended EMI filter design. CRM limits the
maximum currentsof the boost stage diode, MOSFET and inductor. reduces the costs and improves the reliabilityof the circuit. This
device substantially exhibits unity power factor while operatingin
DCM and CRM. The NCP1601 minimizes the required numberof
external components.It incorporates high safety protection features
that make the NCP1601 suitable for robust and compact PFC stages.
Features Near- -Unity Power Factorin DCMor CRM Voltage- -Mode Operation Low Startup and Shutdown Current Consumption Programmable Switching Frequencyfor DCM Synchronization Capability Overvoltage Protection (107%of Nominal Output Level) Undervoltage Protectionor Shutdown
(8%of Nominal Output Level) Programmable Overcurrent Protection Thermal Shutdown with Hysteresis (95/140qC) Two VCC Undervoltage Lockout Hysteresis Options:
4.75Vfor NCP1601A and 1.5Vfor NCP1601B These are Pb- -Free Devices
Typical Applications Electronic Light Ballast AC Adapters TV& Monitors Mid- -Power Applications
