Circuit Description
The evaluation board is configured with a PE22100 transformer driver (U1) and a 782100/55JVC transformer
(T1) in a push-pull configuration.The output from this transformer is then rectified via D1 and D2 to produce an
isolated DC output.
The PE22100 features an internal regulator that supplies the chip will output a nominal 2.6V on C5.
An internal oscillator is generated in the chip and is visible as a triangle wave on C6.
