1) Raise V
BP voltage from 0 V to 6.2 V, doen to 4.5 to 6.2
2) Raise V
IN until cycle skipping occurs at VOUT to measure VFBth
3) Reduce V
IN until cycle skipping stops at VOUT to measure VFBth-. Cable drop compensaion factor is υFB = VFBth / VFBth-
4) Apply 1.5 V at V
IN and measure tFB delay from start of cycle falling edge to the next falling edge

To measure BV
DSS, IDSS1, and IDSS2 follow these steps:
1) Close S1, open S2
2) Power-up V
IN source (16 V)
3) Open S1, close S2
4) Measure I/V characteristics of Drain pin using the curve tracer
