RAA223881 700V Off-line Flyback Regulator Datasheet The RAA223881, an off-line flyback regulator with an integrated 700V power MOSFET, provides a cost-effective solution for high-input voltage applications such as appliances, air conditioners, and general-purpose isolated power supplies.

The flyback regulator operates with a constant switching frequency of 65kHz and employs current mode control.

At light loads, it operates in burst mode to reduce power consumption and uses secondary-side feedb

RAA223881 Features

* an integrated high-voltage (HV) startup for a low system-component count. It also provides frequency dithering to simplify EMI filter design. The device comes in a 7 Ld PDIP package. Features ▪ Integrated with 700V 5Ω MOSFET ▪ Constant frequency PWM operation with current mode control ▪ Burst mode
