♠ TPS61193 Iwakọ LED ikanni mẹta ti o ga julọ
TPS61193 jẹ iṣẹ ṣiṣe giga, kekere-EMI, rọrun-lati-lo awakọ LED pẹlu irọrun lati ṣe atilẹyin fun ọpọlọpọ awọn ohun elo. O ni awọn ifọwọ lọwọlọwọ giga-giga mẹta ti o le ṣe idapo fun agbara lọwọlọwọ giga.
TPS61193 naa ni DC-DC ti a ṣepọ ti n ṣe atilẹyin igbelaruge mejeeji ati iṣẹ ipo SEPIC. Oluyipada naa ni iṣakoso foliteji o wu adaṣe ti o da lori awọn foliteji ori iyẹwu LED lọwọlọwọ. Ẹya yii dinku agbara agbara nipasẹ satunṣe foliteji si ipele ti o kere julọ ni gbogbo awọn ipo. Fun iṣakoso EMI oluyipada DC-DC n ṣe atilẹyin kaakiri fun iyipada igbohunsafẹfẹ ati imuṣiṣẹpọ ita pẹlu pin igbẹhin.
TPS61193 ni iwọn foliteji titẹ sii jakejado lati 4.5 V si 40 V fun atilẹyin to lagbara ti awọn oriṣiriṣi awọn ohun elo. TPS61193 ṣepọ awọn ẹya wiwa aṣiṣe lọpọlọpọ. Ẹrọ naa ṣe atilẹyin ipin didin didin imọlẹ PWM ti 10 000:1 fun 100-Hz input PWM igbohunsafẹfẹ.
