TPS5420 ke phetoho e phahameng ea PWM ea hona joale e kopanyang boemo bo tlase ba N-channel MOSFET. E kenyelelitsoe ho substrate e nang le likarolo tse thathamisitsoeng ke amplifier ea phoso ea motlakase e phahameng e fanang ka ho nepahala ha taolo ea motlakase tlas'a maemo a nakoana; potoloho ea undervoltage-lockout ho thibela ho qala ho fihlela motlakase o kenang o fihla ho 5.5 V; potoloho ea ho qala butle e behiloeng ka hare ho fokotsa maqhubu a inrush; le potoloho ea phepelo ea motlakase ho ntlafatsa karabelo ea nakoana.Ho sebelisa pini ea ENA, hona joale phepelo ea ho koala e fokotsehile ho 18 μA ka tloaelo. Likarolo tse ling li kenyelletsa sesebelisoa se phahameng se sebetsang, ho fokotsa ho feta, ts'ireletso ea overvoltage le ho koala ha mocheso. Ho fokotsa ho rarahana ha moralo le palo ea likarolo tsa kantle, loop ea maikutlo ea TPS5420 e lefshoa ka hare.
Sesebelisoa sa TPS5420 se fumaneha ka har'a sephutheloana sa SOIC sa 8-pin. TI e fana ka limmojule tsa tlhahlobo le sesebelisoa sa software sa Moqapi ho thusa ho fihlela kapele meralo ea phepelo ea motlakase e sebetsang hantle ho kopana le lipotoloho tse matla tsa ntlafatso ea lisebelisoa.
