Inkcazo

I-TPS61088 yi-high-power density, idityaniswe ngokupheleleyo i-synchronous boost converter kunye ne-11-mΩ amandla okutshintsha kunye ne-13-mΩ yokutshintshela isitshintshi sokubonelela ngesisombululo esiphezulu kunye nobukhulu obuncinci kwiinkqubo eziphathekayo.I-TPS61088 inoluhlu olubanzi lwegalelo lombane ukusuka kwi-2.7 V ukuya kwi-12 V ukuxhasa izicelo nge-cell-cell okanye iibhetri ezimbini zeLithium.Isixhobo sine-10-A ikhono lokutshintsha langoku kwaye liyakwazi ukubonelela nge-voltage ephumayo ukuya kwi-12.6 V. I-TPS61088 isebenzisa i-adaptive eguquguqukayo ye-off-time incopho yangoku yokulawula i-topology yokulawula i-voltage output.Ngokwemodareyitha ukuya kwimeko yomthwalo onzima, i-TPS61088 isebenza kwimodi yokumodareyitha ububanzi be-pulse (PWM).Kwimeko yomthwalo okhanyayo, isixhobo sineendlela ezimbini zokusebenza ezikhethwe yi-MODE pin.

Enye yimowudi ye-pulse frequency modulation (PFM) yokuphucula ukusebenza kakuhle kwaye enye inyanzeliswa imo ye-PWM ukunqanda iingxaki zesicelo ezibangelwa kukutshintsha okuphantsi.I-frequency yokutshintsha kwimodi ye-PWM ilungelelaniswa, ukusuka kwi-200 kHz ukuya kwi-2.2 MHz yi-resistor yangaphandle.I-TPS61088 iphinda iphumeze umsebenzi wokuqalisa othambileyo olungiselelweyo kunye nencopho eguqukayo eguqukayo yangoku yokuphela komsebenzi.Ukongeza, isixhobo sibonelela nge-13.2-V yokukhuselwa kwe-overvoltage yemveliso, ukhuseleko lomjikelo-ngomjikelo we-overcurrent, kunye nokukhuselwa kwe-thermal shutdown.I-TPS61088 ifumaneka kwi-4.50-mm × 3.50-mm i-20-pin ye-VQFN iphakheji.
