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.
