Tlhaloso

TPS61088 ke sesebelisoa sa matla a phahameng, se kopantsoeng ka botlalo sa synchronous boost converter se nang le sesebelisoa sa matla sa 11-mΩ le 13-mΩ rectifier switch ho fana ka tharollo e phahameng le ea boholo bo nyane lits'ebetsong tse nkehang habonolo.TPS61088 e na le mefuta e mengata ea ho kenya motlakase ho tloha ho 2.7 V ho ea ho 12 V ho tšehetsa lisebelisoa tse nang le lisele tse le 'ngoe kapa li-betri tsa Lithium tse peli.Sesebelisoa se na le matla a hona joale a 10-A 'me se khona ho fana ka motlakase o tsoang ho 12.6 V. TPS61088 e sebelisa adaptive kamehla off-time peak current control topology ho laola motlakase oa tlhahiso.Boemong bo itekanetseng ho isa boemong bo boima, TPS61088 e sebetsa ka mokhoa oa pulse width modulation (PWM).Boemong ba boima bo bobebe, sesebelisoa se na le mekhoa e 'meli ea ts'ebetso e khethiloeng ke phini ea MODE.

E 'ngoe ke mokhoa oa pulse frequency modulation (PFM) ho ntlafatsa ts'ebetso mme e' ngoe e qobelloa mokhoa oa PWM ho qoba mathata a ts'ebeliso a bakoang ke maqhubu a tlase a ho fetoha.Maqhubu a ho chencha ka mokhoa oa PWM a ka fetoha, ho tloha ho 200 kHz ho ea ho 2.2 MHz ka khanyetso ea kantle.TPS61088 e boetse e sebelisa ts'ebetso e ka khonehang ea ho qala ka bonolo le ts'ebetso e feto-fetohang e feto-fetohang ea moeli oa hona joale.Ntle le moo, sesebelisoa se fana ka ts'ireletso ea 13.2-V ea tlhahiso ea overvoltage, ts'ireletso ea cycle-by-cycle overcurrent, le ts'ireletso ea ho tima mocheso.TPS61088 e fumaneha ka har'a sephutheloana sa VQFN sa 4.50-mm × 3.50-mm 20-pin VQFN.
