TPS40055 Description
The TPS4005x is a family of high-voltage, wideinput (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 feedforward, high-side current limit, and loop pensation. The TPS4005x uses voltage feedforward control techniques to provide good line regulation over the wide (4:1)...
