Cur síos
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.
Tá frithdhúnadh undervoltage socraithe go hinmheánach ag 2.5 V, ach is féidir é a mhéadú ag baint úsáide as an bioráin chumasaithe. Tá an rampa tosaithe voltais aschuir á rialú ag an biorán tosaithe mall ar féidir a chumrú freisin le haghaidh seicheamhaithe/rianaithe. Léiríonn comhartha maith cumhachta draein oscailte go bhfuil an t-aschur laistigh de 94 faoin gcéad go 107 faoin gcéad dá voltas ainmniúil.
Ceadaíonn raon minicíochta athrú leathan éifeachtacht agus méid na gcomhpháirteanna seachtracha a optimized.Frequency huaire ar ais agus múchadh teirmeach a chosnaíonn an chuid le linn riocht ró-ualach.
