TOPSwitch-II Family Functional Description
TOPSwitch is a self biased and protected linear control current-
to-duty cycle converter with an open drain output. High
Auto-restart
efficiency is achieved through the use of CMOS and integration
of the maximum number of functions possible. CMOS process

significantly reduces bias currents as compared to bipolar or
discrete solutions. Integration eliminates external power
resistors used for current sensing and/or supplying initial start-
up bias current.
During normal operation, the duty cycle of the internal output
MOSFET decreases linearly with increasing CONTROL pin
current as shown in Figure 4. To implement all the required
control, bias, and protection functions, the DRAIN and
