MC33232 Power Factor Controller The MC33232 is the monolithic Integrated Circuit using the SMARTMOS® process as the new technology. And is active power factor controller specially design for use as off−line power converter application. This integrated circuit features an internal startup timer for stand−alone application, a one quadrant multiplier for near unity power factor, zero current detector to ensure critical condition operation, transconductance error amplifier, quickstart circuit for enhanced startup, trimmed internal bandgap reference, current sensing comparator, a totem pole output ideally suited for drive a power MOSFET, and a one shot−rigger circuit to eliminate a problem at the light loading. Also included are protective features consisting of an overvoltage comparator to eliminate runaway output voltage due to removal, and a protect circuit to eliminate thermal runaway. This device is available in dual−in−line and surface mount plastic package. http://onsemi.com SILICON MONOLITHIC INTEGRATED CIRCUIT MARKING DIAGRAMS PDIP−8 P SUFFIX CASE 626 Features • • • • • • • • • • • One Shot−trigger Circuit to Eliminate a Problem at the Light Loading Overvoltage Comparator Eliminates Runaway Output Voltage Quickstart Circuit for Enhanced Startup Internal Startup Timer One Quadrant Multiplier Zero Current Detector Trimmed 2% Internal Bandgap Reference Totem Pole Output with High State Clamp Undervoltage Lockout with 6.0 V of Hysteresis Low Startup and Operating Current Pb−Free Packages are Available MC33232P AWL YYWWG 8 SOIC−8 D SUFFIX CASE 751 33232 ALYW G 1 A WL or L Y WW or W G or G = Assembly Location = Wafer Lot = Year = Work Week = Pb−Free Package PIN ASSIGNMENT Voltage Feedback Input 1 8 VCC Compensation 2 7 Drive Output Multiplier Input Current Sense Input 3 6 4 5 GND Zero Current Detect Input ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 2 of this data sheet. © Semiconductor Components Industries, LLC, 2007 January, 2007 − Rev. 2 1 Publication Order Number: MC33232/D MC33232 1.4 V 28 V 8 5.3 V 5 + Zero Current Detector 1.6 V/1.4 V 2.5 V Reference + POR UVLO Timer 16 V 7 TSD + One−shot Current Sensor 2p 5 k 4 + Over Voltage Comparator Vref + 1.5 V 1.067 Vref Multiplier Err Amp 3 1 Quickstart 2 6 Figure 1.
