features . These features allow for both flexibility as well as precision in it’s application to a circuit. Critical ponents of the internal circuitry are designed for high accuracy, which allows for precise power and current limiting, therefore minimizing the amount of overdesign necessary for the power stage ponents. The NCP1650 is designed with a true power limiting circuit that will maintain excellent power factor even in constant power mode. It also contains features that allow for fast transient response to changing load currents and line voltages. Features - Fixed Frequency Operation - Average Current Mode PWM - Continuous or Discontinuous Mode Operation - Fast Line/Load Transient pensation - True Power Limiting Circuit - High Accuracy Multipliers - Undervoltage Lockout - Overvoltage Limiting parator - Brown Out Protection - Ramp pensation Does Not Affect Oscillator Accuracy - Operation from 25 to 250 k Hz - This is a Pb- Free Device Typical Applications - Server Power Converters - Front End for Distributed Power Systems .onsemi. 16 1 SO- 16 D SUFFIX CASE 751B MARKING DIAGRAM NCP1650G AWLYWW A = Assembly Location WL = Wafer Lot Y = Year WW = Work Week G = Pb- Free Package PIN CONNECTIONS Vin 1 Vref 2 AC P 3 AC REF 4 AC INPUT 5 FB/SD 6 LOOP P 7 PP 8 16 OUTPUT 15 GND 14 CT 13 RAMP P 12 IS- 11 Iavg- fltr 10 Iavg 9 Pmax (Top View) ORDERING INFORMATION Device Package Shipping† NCP1650DR2G SOIC- 16 2500/Tape & Reel (Pb- Free) †For information on tape and reel specifications, including part orientation and tape sizes, please refer to our Tape and Reel Packaging Specifications Brochure, BRD8011/D. © Semiconductor ponents Industries, LLC, 2015 March,...
