TPS54140ADGQ

The TPS54140A device is a 42-V, 1.5-A, step-down regulator with an integrated high-side MOSFET Current-mode control provides simple external compensation and flexible component selection. A low ripple-pulse skip mode reduces the no-load,regulated output supply current to 116 μA. Using the enable pin, shutdown supply current is reduced to 1.3 μA.

Podnapetostna blokada je interno nastavljena na 2,5 V, vendar jo je mogoče povečati z uporabo zatiča za omogočanje. Zagonska rampa izhodne napetosti je nadzorovana s pinom za počasni zagon, ki ga je mogoče konfigurirati tudi za zaporedje/sledenje. Signal dobre moči odprtega odtoka kaže, da je izhod v območju od 94 do 107 odstotkov nazivne napetosti.

Široko preklopno frekvenčno območje omogoča optimizacijo učinkovitosti in velikosti zunanjih komponent. Frekvenčni preklop in termični izklop ščitita del med stanjem preobremenitve.
