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-forward, high-side current limit, and loop compensation.
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 using an internal fault counter for longer duration overloads.
