90W(19V/4.74A)适配器参考设计

This section shows a design example of 90W (19V/4.74A) adaptor using QR PWM controller FAN6300/A/H and boundary conduction mode PFC controller FAN6961. The PFC output voltage is 260V at low AC input voltage, 400V at high AC input voltage. From the specification, all critical components are treated and final measurement results are given.
