♠ TPS56339 4.5-V ukuya 24-V Igalelo, 3-A Imveliso Synchronous Buck Converter
I-TPS56339 yi-4.5-V ukuya kwi-24-V yoluhlu lwe-voltage yegalelo, i-3-A i-synchronous buck converter. Isixhobo sibandakanya ii-MOSFET ezimbini ezidibeneyo zokutshintsha, imbuyekezo ye-loop yangaphakathi kunye ne-5-ms yangaphakathi ethambileyo-ukuqala ukunciphisa ukubalwa kwamacandelo. Ngokusebenzisa iphakheji ye-SOT-23 (6), isixhobo sifezekisa ubuninzi bamandla aphezulu kwaye sinikezela ngeenyawo ezincinci kwi-PCB.
I-TPS56339 isebenzisa i-Advanced Emulated Current Mode (AECM) ulawulo olunokufumana impendulo yesikhashana ngokukhawuleza kunye nefrikhwensi esisigxina. Ukulungelelaniswa kwe-loop ye-adaptive yangaphakathi kuphelisa imfuno yembuyekezo yangaphandle phezu koluhlu olubanzi lwemveliso yombane.
Umda we-Cycle-by-cycle yangoku kwi-high-side ikhusela isixhobo kwiimeko zangoku zokugqithiswa kwaye ziphuculwe ngumda ophantsi wokukhangela okhoyo othintela ukubaleka kwangoku. Ukukhuselwa kwe-Hiccup kuya kubangelwa phantsi kwe-undervoltage kunye nokhuseleko lokuvalwa kwe-thermal.
