2.2.2 Step 2: Input Supply

Power up the input supply (0V to 80V). The D2 diode lights up after the input supply is powered up. Observe the output voltage on the sense signals (TP2, TP3). Adjust the PWM duty cycle such that the output is of the desired voltage. Load the output with an appropriate electronic load.

Note:

The PWM duty cycle must be adjusted to compensate for the losses when the supply is loaded.
