FIGURE 18. WOC OPERATION
Channel 1 is Vgate, Channel 2 is the pulse generator output
and Channel 3 is Vout. Note how Vgate gets immediately
pulled down to zero volts up on load application.
In CR mode, however, Vgate always remains above zero
volts because WOC comparator never trips. This can be
seen on the following scope shot:
FIGURE 19. CURRENT REGULATION OPERATION
It is also important to note that in WOC mode, although
Vgate gets pulled down to zero initially, the gate is quickly
released and slowly rises until the CR amplifier takes control.
