Circuit design of 2.4W low cost and high efficiency power supply
Summary:
The LinkSwitch-LP flyback power supply converts AC input voltages from 90 VAC to 265 VAC into a single isolated DC output voltage. The power supply output is 12 V, 200 mA (2.4 W) with constant voltage/constant current (CV/CC) characteristics. Typical applications include Power Supplies for microwave ovens and other white goods.
