TOPSwitch-II Family Functional Description

TOPSwitch is a self biased and protected linear control cur-

rent-to-duty cycle converter with an open drain output. High

efﬁciency is achieved through the use of CMOS and integra-

tion 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 CON-

TROL pins each perform several functions as described

below. Refer to Figure 2 for a block diagram and to Figure 6

for timing and voltage waveforms of the TOPSwitch inte-

grated circuit.
