NCP1606

DATA SHEET www.onsemi.com Cost Effective Power Factor Controller NCP1606 The NCP1606 is an active power factor controller specifically designed for use as a pre−converter in electronic ballasts, ac−dc adapters and other medium power off line converters (typically up to 300 W). It embeds a Critical Conduction Mode (CRM) scheme that substantially exhibits unity power factor across a wide range of input voltages and power levels. Housed in a SOIC−8 package, the NCP1606 minimizes the number of external components. Its integration of comprehensive safety protection features makes it an excellent driver for rugged PFC stages. General Features “Unity” Power Factor No Need for Input Voltage Sensing Latching PWM for Cycle by Cycle On Time Control (Voltage Mode) High Precision Voltage Reference (±1.6% over temperature ranges) Very Low Startup Current Consumption (≤ 40 mA) Low Typical Operating Current (2.1 mA) −500 mA / +800 mA Totem Pole Gate Driver Undervoltage Lockout with Hysteresis Pin to Pin Compatible with Industry Standards Safety Features Programmable Overvoltage Protection Protection against Open Loop (Undervoltage Protection) Accurate and Programmable On Time Limitation Overcurrent Limitation Typical Applications Electronic Light Ballast AC Adapters, TVs, Monitors All Off Line Appliances Requiring Power Factor Correction 8 1 SO−8 D SUFFIX CASE 751 MARKING DIAGRAM 8 1606x ALYW G 1 x = A or B A = Assembly Location L = Wafer Lot Y = Y...
