© Semiconductor Components Industries, LLC, 2009 June, 2009 − Rev. 3 1 Publication Order Number: NCP1654/D NCP1654 Power Factor Controller for Compact and Robust, Continuous Conduction Mode Pre-Converters The NCP1654 is a controller for Continuous Conduction Mode (CCM) Power Factor Correction step−up pre−converters. It controls the power switch conduction time (PWM) in a fixed frequency mode and in dependence on the instantaneous coil current. Housed in a SO8 package, the circuit minimizes the number of external components and drastically simplifies the PFC implementation. It also integrates high safety protection features that make the NCP1654 a driver for robust and compact PFC stages like an effective input power runaway clamping circuitry. Features • IEC61000−3−2 Compliant • Average Current Continuous Conduction Mode • Fast Transient Response • Very Few External Components • Very Low Startup Currents (<75 mA) • Very Low Shutdown Currents (< 400 mA) • Low Operating Consumption • ±1.5 A Totem Pole Gate Drive • Accurate Fully Integrated 65/133/200 kHz Oscillator • Latching PWM for cycle−by−cycle Duty−Cycle Control • Internally Trimmed Internal Reference • Undervoltage Lockout with Hysteresis • Soft−Start for Smoothly Startup Operation • Shutdown Function • Pin to Pin Compatible with Industry Standard • This is a Pb−Free Device Safety Features • Inrush Currents Detection • Overvoltage Protection • Undervoltage Detection for Open Loop Detection or Shutdown • Brown−Out Detection • Soft−Start • Accurate Overcurrent Limitation • Overpower Limitation Typical Applications • Flat TVs, PC Desktops • AC Adapters • White Goods, other Off−line SMPS PIN CONNECTIONS http://onsemi.com MARKING DIAGRAM SO−8 D SUFFIX CASE 751 1 Ground 8 Driver 2 VM 3 CS 4 Brown−Out 7 VCC 6 Feedback 5 Vcontrol (Top View) xx = 65, 133 or 200 A = Assembly Location L = Wafer Lot Y = Year W = Work Week G = Pb−Free Package 1 8 54Bxx ALYW G 1 8 SO−8 (Pb−Free) Device Package Shipping† ORDERING INFORMATION NCP1654BD65R2G 2500 / Tape & Reel †For information on tape and reel specifications, including part orientation and tape sizes, please refer to our Tape and Reel Packaging Specification Brochure, BRD8011/D.
