AP8022-AC-DC OFF LINE SMPS PRIMARY SWITCHER IC

Nowadays, Power devices defined as innovative technology enabling future development of power converters and systems. These Power Device IC capable of precisely controlling electrical energy from the source to the load according to the load demand, at high efficiency, and with outstanding reliability. A power device IC designed as a semiconductor device acts as a switch in power electronics (ex: switch-mode power supply). Such a type of device known as the power device.  Or when used in an integrated circuit, referred to as the power IC.

The AP8022 Power Switch IC designed as an integrated Pulse Width Modulators (PWM) controller and power MOSFET designed explicitly for high-performance offline Switch Mode Power Supplies (SMPS). Thus operated with minimal external components. Both devices integrated as high voltage power switching regulators which combine a MOSFET with a current mode PWM control block. This integrated PWM controller consists of a fixed oscillator with frequency modulation for reduced EMI. It features complete protection coverage with automatic self-recovery features including Cycle-by-Cycle current limiting (OCP), over-voltage protection (OVP), over-temperature protection (OTP), and also soft-start. Moreover, the Burst mode operation feature of this device offers the possibility to operate in standby mode without extra components. This is the advanced platform for low standby-power and also cost-effective flyback converter.
