TPS54229 waa laqabsiga qaab-waqtiga ku jira ee D-CAP2 TheTPS54229 waxay awood u siinaysaa naqshadeeyayaasha nidaamka inay dhamaystiraan hagayaasha baska korantada ee qalabka dhamaadka ugxan-sidaha oo leh qiime wax ku ool ah, tiro yar oo ka kooban, xal hadda taagan oo hooseeya. Xakamaynta ugu weyn ee TPS54229 waxay isticmaashaa qaabka D-CAP2™ kaas oo bixiya jawaab degdeg ah oo aan lahayn qaybo magdhow dibadeed ah. TPS54229 waxa kale oo ay leedahay wareeg lahaanshaha oo awood u siinaya aaladda in uu la qabsado labada awood wax soo saar ee iska caabin ah oo hooseeya (ESR), sida POSCAP ama SP-CAP, iyo capacitors ESR aadka u hooseeya. Qalabku wuxuu ka shaqeeyaa 4.5-V ilaa 18-VIN gelinta. Korontada wax-soo-saarka waxaa lagu habayn karaa inta u dhaxaysa 0.76 V iyo 7 V. Qalabku wuxuu kaloo leeyahay waqti bilawga jilicsan la hagaajin karo. TPS54229 waxaa laga heli karaa xirmada 8-pin ee DDA, waxaana loogu talagalay inay ka shaqeyso -40°C ilaa 85°C.
