NCP1616A2DR2G ON Semiconductor

NCP1616 High Voltage High Efficiency Power Factor Correction Controller The NCP1616 is a high voltage PFC controller designed to drive PFC boost stages based on an innovative Current Controlled www.onsemi.com Frequency Foldback (CCFF) method. In this mode, the circuit operates in critical conduction mode (CrM) when the inductor current exceeds a programmable value. When the current is below this preset 9 level, the NCP1616 linearly decays the frequency down to a minimum 1 of about 26 kHz at the sinusoidal zerocrossing. CCFF maximizes the SOIC9 efficiency at both nominal and light load. In particular, the standby CASE 751BP losses are reduced to a minimum. Innovative circuitry allows near unity power factor even when the switching frequency is reduced. MARKING DIAGRAM The integrated high voltage startup circuit eliminates the need for 9 external startup components and consumes negligible power during 1616xx normal operation. Housed in a SOIC9 package, the NCP1616 ALYWX incorporates the features necessary for robust and compact PFC stages, with few external components. 1 General Features 1616xx = Specific Device Code High Voltage StartUp Circuit with Integrated Brownout Detection xx = A1 or A2 A = Assembly Location Input to Force Controller into Standby Mode L = Wafer Lot Skip Mode Near the Line Zero Crossing Y = Year W = Work Week Fast Line / Load Transient Compensation = PbFree Package Valley Switching for Improved Efficiency High Drive Capability: 500 mA/+800 mA Wide V Range: from 9.5 V to 28 V PIN CONNECTIONS CC Input Voltage Range Detection FB HV Input X2 Capacitor Discharge Circuitry STDBY/FAULT VCC VControl This is a Pb and Halogen Free Device FFControl DRV Safety Features CS/ZCD GND Soft Overvoltage Protection NCP1616 9 Pins (Top View) Line Overvoltage Protection Overcurrent Protection ORDERING INFORMATION Open Pin Protection for FB and STDBY/FAULT Pins See detailed ordering and shipping information in the package Internal Thermal Shutdown dimensions section on page 4 of this data sheet.
