isinxephezelo
izingxenye.I-TPS54627 nayo inobunikazi
isifunda esivumela idivayisi ukuthi isebenzise kokubili okuphansi
i-equivalent-series-resistance (ESR) okukhipha ama-capacitor,
njenge-POSCAP noma i-SP-CAP, kanye ne-ultra-low ESR
ama-capacitors e-ceramic.
Idivayisi isebenza kusuka ku-4.5-V kuya ku-18-V VIN okokufaka.
