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):
AP3965 for 5W Adapter and 3W Buck
AP3966 for 10W Adapter and 4.5W Buck
AP3971 for 12W Adapter and 5W Buck
• Totally Lead-free & Fully RoHS Compliant (Note 2 & 3)
• Halogen and Antimony Free. “Green” Device (Note 4)

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.
