NCP1602DCCSNT1G ON Semiconductor

NCP1602 Enhanced, High-Efficiency Power Factor Controller The 6pin PFC controller NCP1602 is designed to drive PFC boost stages. It is based on an innovative Valley Synchronized Frequency Foldback (VSFF) method. In this mode, the circuit classically www.onsemi.com operates in Critical conduction Mode (CrM) when V voltage control exceeds a programmable value V . When V is below this ctrl,FF control preset level V , the NCP1602 (versions B** and D** ) linearly ctrl,FF TSOP6 decays the frequency down to about 30 kHz until V reaches the control SN SUFFIX SKIP mode threshold. VSFF maximizes the efficiency at both CASE 318G 1 nominal and light load. In particular, the standby losses are reduced to a minimum. Like in FCCrM controllers, internal circuitry allows MARKING DIAGRAM nearunity power factor even when the switching frequency is reduced. Housed in a TSOP6 package, the circuit also incorporates the features necessary for robust and compact PFC stages, with few XXX AYW external components. 1 General Features NearUnity Power Factor XXX = Specific Device Code A = Assembly Location Critical Conduction Mode (CrM) Y = Year Valley Synchronized Frequency Foldback (VSFF): Low Frequency W = Work Week = PbFree Package Operation is Forced at Low Current Levels Works With or Without a Transformer w/ ZCD Winding (simple inductor) (Note: Microdot may be in either location) Ontime Modulation to Maintain a Proper Current Shaping in VSFF Mode Skip Mode at Very Low Load Current (versions B** and D** ) PIN CONNECTIONS Fast Line / Load Transient Compensation (Dynamic Response Enhancer) VCTRL 1 6 FB Valley Turnon High Drive Capability: 500 mA / +800 mA 2 5 GND V CC V Range: from 9.5 V to 30 V CC CS / ZCD 3 4 DRV Low Startup Consumption for: **C & **D Versions: Low Vcc Startup level (10.5 V) (Top View) **A & **B Versions: High Vcc Startup level (17.0 V) Line Range Detection for Reduced Crossover Frequency Spread ORDERING INFORMATION This is a PbFree Device See detailed ordering, marking and shipping information in the package dimensions section on page 2 of this data sheet.
