The AP3971P7-G1 from Diodes Incorporated is a primary side regulation controller and high voltage transistor designed for off-line power supplies up to 12W or non-isolated buck applications up to 5W. It operates using pulse frequency modulation (PFM) to provide accurate constant voltage and constant current (CV/CC) regulation without requiring secondary control circuitry or an opto-coupler.
Key electrical specifications include an output power rating of 12W, an operating voltage range of 5.3V to 22V, and an operating frequency of 60kHz. The device integrates a 700V CBO NPN transistor and features built-in short circuit and over-temperature protection. It also includes an internal cable compensation function for tight constant voltage regulation and random frequency modulation for low EMI.
This component is housed in a 7-PDIP package and is designed for through-hole mounting. It is suitable for applications such as adapters, set-top boxes, auxiliary supplies, and appliances. The solution offers a reduced component count, smaller size, and lower total cost compared to traditional designs.
