♠ TPS54302 4.5-V ukuya 28-V Igalelo, 3-A Imveliso, EMI-Friendly Synchronous Step-Down Converter
Isixhobo se-TPS54302 yi-4.5-V ukuya kwi-28-V yoluhlu lwe-voltage yegalelo, i-3-A i-synchronous buck converter. Isixhobo sibandakanya iiFET ezimbini ezidibeneyo zokutshintsha, i-loop yangaphakathiimbuyekezo, kunye ne-5-ms isiqalo esithambileyo sangaphakathi sokunciphisa inani lecandelo.
Ngokudibanisa ii-MOSFETs kunye nokusebenzisa ipakethe ye-SOT-23, isixhobo se-TPS54302 sifezekisa uxinano lwamandla aphezulu kwaye sinikezela ngeenyawo ezincinci kwi-PCB.
Ukuphunyezwa kwe-Eco-mode ephucukileyo kwandisa ukusebenza kakuhle komthwalo wokukhanya kwaye kunciphisa ilahleko yamandla.
Kwisixhobo se-TPS54302, i-frequency spread spectrum operation yaziswa ukuze kuncitshiswe i-EMI.
Umda womjikelo ngomjikelo wangoku kuwo omabini amacala aphezulu e-MOSFET ikhusela umguquli kwimeko yomthwalo omninzi kwaye iphuculwe ngumda wangoku we-MOSFET wamavili osimahla othintela ukubaleka kwangoku. Ukukhuselwa kwe-Hiccup mode kubangelwa ukuba imeko ye-overcurrent iqhubekile ixesha elide kunexesha langoku.
