DESCRIPTION  
The TPS4005x is a family of high-voltage, wide input  
(8 V to 40 V), synchronous, step-down controllers.  
The TPS4005x family offers design flexibility with a  
variety of user-programmable functions, including  
soft-start, UVLO, operating frequency, voltage feed-

compensation.  
TPS40055 Source/Sink  
The TPS4005x uses voltage feed-forward control  
techniques to provide good line regulation over the  
wide (4:1) input voltage range, and fast response to  
input line transients. Near-constant modulator gain  
with input variation eases loop compensation. The  
externally programmable current limit provides pulse-  
by-pulse current limit, as well as hiccup mode  
operation utilizing an internal fault counter for longer  
duration overloads.
