I-TPS5420 sisiguquli se-PWM esiphezulu semveliso-yangoku esidibanisa ukuxhathisa okuphantsi kwicala eliphezulu le-N-channel MOSFET.Ibandakanyiwe kwi-substrate eneempawu ezidwelisiweyo yi-amplifier yempazamo yombane osebenza kakhulu obonelela ngokuchaneka kokulawulwa kombane oqinileyo phantsi kweemeko ezidlulayo;i-undervoltage-lockout circuit ukuthintela ukuqala kuze kube yilapho igalelo lombane lifikelela kwi-5.5 V;iseti yangaphakathi yokucotha-isiqalo sesekethe ukukhawulela imisinga yokungena;kunye ne-voltage feed-forward circuit ukuphucula impendulo yesikhashana.Usebenzisa iphini ye-ENA, umbane wokubonelela ngokuvala uyancipha ukuya kwi-18 μA ngokuqhelekileyo.Ezinye izinto zibandakanya ukusebenza okuphezulu okusebenzayo, ukukhawulwa kwe-overcurrent, ukukhuselwa kwe-overvoltage kunye nokuvalwa kwe-thermal.Ukunciphisa ukuntsokotha koyilo kunye nokubalwa kwecandelo langaphandle, i-TPS5420 loop yempendulo ihlawulwa ngaphakathi.
Isixhobo se-TPS5420 sifumaneka ngokulula ukusebenzisa iphakheji ye-SOIC ye-8-pin.I-TI ibonelela ngeemodyuli zovavanyo kunye nesixhobo sesoftware yoMyili ukunceda ngokukhawuleza ukufezekisa uyilo lonikezelo lwamandla olusebenza kakhulu ukuhlangabezana nemijikelo yophuhliso lwezixhobo ezindlongo.
