DESCRIPTION

AP8025 is based on high-voltage synchronous rectifier architecture, integrated with PFM controller and 650V high-reliability MOSFET，specifically designed for small power non-isolated switching power supply. AP8025 has internal high voltage start-up and self-supply circuit, and complete intelligent protections including Over Current Protection (OCP), Under Voltage Lockout (UVLO) and Over Temperature Protection (OTP). Excellent EMI performance could be achieved with Pulse Frequency Modulation.

The AP8025 is available in SOP7 and DIP7 packages.
