A Product Line of Diodes Incorporated AP3965/66/71 PRIMARY SIDE POWER SWITCHER FOR FLYBACK/NON-ISOLATED BUCK SMPS Description The AP3965/66/71 consists of a primary side regulation controller and a high voltage transistor, and is specially designed for off-line power supplies within 12W output power or non-isolated buck applications within 5W. Typical applications include adapter for ADSL, auxiliary supplies or open frame types for appliances. The AP3965/66/71 operates at pulse frequency modulation (PFM), and provides accurate constant voltage, constant current (CV/CC) regulation without requiring an opto-coupler and secondary control circuitry. It has internal cable compensation function for tight constant voltage regulation. The AP3965/66/71 solution has fewer component numbers, smaller size, and lower total cost. The AP3965 is packaged in SO7. The AP3966/71 is available in PDIP-7. Features • Primary Side Control for Eliminating Opto-coupler and Secondary CV/CC Control Circuitry • Built-in NPN Transistor with 700VCBO • Low Start-up Current: 0.2µA (Typ) • Internal Output Cable Voltage Drop Compensation • Random Frequency Modulation for Low EMI • Short Circuit Protection • Low Total Cost Solution • Output Power Range (Note 1): ƒ AP3965 for 5W Adapter and 3W Buck ƒ AP3966 for 10W Adapter and 4.5W Buck ƒ AP3971 for 12W Adapter and 5W Buck • Totally Lead-free & Fully RoHS Compliant (Note 2 & 3) • Halogen and Antimony Free. “Green” Device (Note 4) Pin Assignments M Package (SO7) CPC 1 FB 2 VCC 3 CS 4 For AP3965 7 GND 6C 5C P7 Package (PDIP-7) CPC 1 FB 2 7 GND VCC 3 6C CS 4 5C For AP3966/71 Applications • Adapters • Set Top Boxes • Auxiliary Supplies • Appliances Notes: 1. Typical continuous power in a non-ventilated enclosed adapter measured at +50°C ambient. 2. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant. 3. See http://www.diodes.com/quality/lead_free.html for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green" and Lead-free. 4. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and <1000ppm antimony compounds.
