imbuyekezo
amacandelo.I-TPS54627 nayo inobunikazi
isekethe eyenza ukuba isixhobo samkeleke kuzo zombini ezisezantsi
i-equivalent-series-resistance (ESR) i-capacitors yemveliso,
njenge-POSCAP okanye i-SP-CAP, kunye ne-ultra-low ESR
capacitors ceramic.
Isixhobo sisebenza ukusuka kwi-4.5-V ukuya kwi-18-V igalelo leVIN.
Umbane ophumayo unokucwangciswa phakathi
I-0.76 V kunye ne-5.5 V. Isixhobo siphinde sibe ne-
ixesha lokuqalisa elithambileyo elinokulungiswa.I-TPS54627 iyafumaneka
kwiphakheji ye-8 ye-SO PowerPAD, kwaye yenzelwe ukuba
isebenza ukusuka ku-40°C ukuya kuma-85°C.
