♠ TPS53355 1.5-V ukuya 15-V Igalelo (4.5-V ukuya 25-V bias), 30-A Synch Step-down SWIFT™ Converter nge Eco-mode™
I-TPS53355 yimowudi ye-D-CAP™, i-30-A i-synchronous switcher ene-MOSFETs ezidibeneyo. Yenzelwe ukusetyenziswa lula, ukubalwa kwecandelo langaphandle eliphantsi, kunye neenkqubo zamandla ezithatha indawo.
Esi sixhobo sine-5-mΩ/2-mΩ i-MOSFETs edibeneyo, i-1% echanekileyo ye-0.6-V ireferensi, kunye ne-boost switch edibeneyo. Isampulu yeempawu ezikhuphisanayo zibandakanya: I-1.5-V ukuya kwi-15-V ebanzi yokuguqulwa kwamandla ombane, ukubalwa kwecandelo langaphandle eliphantsi kakhulu, ulawulo lwemowudi ye-DCAP™ yesantya esiphezulu esikhawulezayo, ukusebenza kwemowudi ye-auto-skip, ulawulo lwangaphakathi oluthambileyo, i-frequency ekhethiweyo, kwaye akukho mfuneko yembuyekezo.
I-voltage ye-conversion ye-conversion isukela kwi-1.5 V ukuya kwi-15 V, uluhlu lwe-voltage yokubonelela luvela kwi-4.5 V ukuya kwi-25 V, kunye noluhlu lwe-voltage ye-voltage luvela kwi-0.6 V ukuya kwi-5.5 V. Isixhobo sifumaneka kwi-6-mm × 5-mm, i-22-pin QFN iphakheji.
