Коммутационные контроллеры TPS40055PWPG4

DC/DC контроллер , режим напряжения, 8В до 40В, 1 выход, синхронный понижающий, 1МГц, HTSSOP-16

The TPS40055PWPG4 is a synchronous step-down Buck Controller 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. It 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.
