MC34262, MC33262 Power Factor Controllers The MC34262/MC33262 are active power factor controllers specifically designed for use as a preconverter in electronic ballast and in off−line power converter applications. These integrated circuits feature an internal startup timer for stand−alone applications, a one quadrant multiplier for near unity power factor, zero current detector to ensure critical conduction operation, transconductance error amplifier, quickstart circuit for enhanced startup, trimmed internal bandgap reference, current sensing comparator, and a totem pole output ideally suited for driving a power MOSFET. Also included are protective features consisting of an overvoltage comparator to eliminate runaway output voltage due to load removal, input undervoltage lockout with hysteresis, cycle−by−cycle current limiting, multiplier output clamp that limits maximum peak switch current, an RS latch for single pulse metering, and a drive output high state clamp for MOSFET gate protection. These devices are available in dual−in−line and surface mount plastic packages. http://onsemi.com POWER FACTOR CONTROLLERS MARKING DIAGRAMS Features • • • • • • • • • • Overvoltage Comparator Eliminates Runaway Output Voltage 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 Supersedes Functionality of SG3561 and TDA4817 This is a Pb−Free and Halide−Free Device Zero Current Detector 5 2.5V Reference Undervoltage Lockout Zero Current Detect Input VCC 8 PDIP−8 P SUFFIX CASE 626 8 MC3x262P AWL YYWWG 1 1 8 8 SOIC−8 D SUFFIX CASE 751 1 x A WL, L YY, Y WW, W G G 3x262 ALYW G 1 = 3 or 4 = Assembly Location = Wafer Lot = Year = Work Week = Pb−Free Package = Pb−Free Package 8 PIN CONNECTIONS Drive Output 7 Multiplier, Latch, PWM, Timer, & Logic Overvoltage Comparator + Error Amp Multiplier Input 3 4 Current Sense Input Voltage Feedback Input Compensation Multiplier Input Current Sense Input 1 8 VCC 2 7 Drive Output 6 GND 5 Zero Current Detect Input 3 4 (Top View) 1.08 Vref ORDERING INFORMATION + Vref Multiplier Voltage Feedback 1 Input See detailed ordering and shipping information in the package dimensions section on page 17 of this data sheet.
