2.2.1 Step 1: Driver Bias Supply

Power up the driver bias supply (5.5V to 10V) first. The D1 diode lights up after the driver bias supply comes up. After this step, apply PWM pulses using one of the three methods and observe the PWM signals on Pin 2 and Pin 3 of J6. Verify that the PWM signal for the high and low side are of the desired frequency (100kHz to 1MHz) depending on the input voltage and load). Also observe the default dead time between the high-to-low and low-to-high PWM transitions.
