Kev piav qhia
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.
Undervoltage lockout yog teem rau sab hauv ntawm 2.5 V, tab sis tuaj yeem nce ntxiv siv tus pin pab. Qhov tso zis hluav taws xob pib qhov chaw nres tsheb yog tswj los ntawm tus pin pib qeeb uas tuaj yeem raug teeb tsa rau kev sib txuas / taug qab. Qhov qhib lub zog hluav taws xob zoo teeb liab qhia tias cov zis yog nyob rau hauv 94 feem pua rau 107 feem pua ntawm nws cov nominal voltage.
Kev sib hloov ntau zaus tso cai rau kev ua tau zoo thiab cov khoom siv sab nraud kom zoo dua qub.Frequency quav rov qab thiab thermal shutdown tiv thaiv ib feem thaum muaj xwm txheej dhau.
