Summary:

working principle

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 2 V, 1.5 A (3 W) with constant voltage/constant current (CV/CC) characteristics. Typical applications include those that use a single rechargeable battery for an electric hair clipper and a repairer.
