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.
