Isekethe Entsha Yoqobo Ehlanganisiwe TPS63070RNMR

Isithombe Esifakiwe Esisha Soqobo Esihlanganisiwe Se-TPS63070RNMR

incazelo emfushane:

I-TPS6307x iyi-converter esebenza kahle kakhulu, ephansi ethule yamanje ye-buck-boost efanele izinhlelo zokusebenza lapho i-voltage yokufaka ingaba phezulu noma ibe phansi kune-voltage ephumayo.Ama-currents okukhiphayo angaya phezulu aze afike ku-2 A kumodi ye-boost nakwimodi yebhali.Isiguquli se-buck-boost sisekelwe kusilawuli se-fixed frequency, pulse-width modulation (PWM) sisebenzisa ukulungiswa okuvumelanayo ukuze kutholwe ukusebenza kahle okuphezulu.Kumaza okulayisha aphansi, isiguquli singena Kumodi Yokonga Amandla ukuze sigcine ukusebenza kahle okuphezulu phezu kobubanzi bamanje bomthwalo.Isiguquli singacishwa ukuze kuncishiswe ukuphuma kwebhethri.Ngesikhathi sokuvala, umthwalo uyanqanyulwa ebhethrini.Idivayisi itholakala ngephakheji ye-QFN engu-2.5 mm x 3 mm.

Isingeniso

I-switching regulator (i-DC-DC converter) iyisilawuli (ukunikezwa kwamandla okuzinzile).Isilawuli esishintshayo singaguqula i-voltage ye-input direct current (DC) ibe ivolthi efiswayo yamanje eqondile (DC).
Kumshini kagesi noma kwenye into, isilawuli esishintshayo sithatha indima yokuguqula i-voltage isuka ebhethrini noma komunye umthombo wamandla iye kumandla kagesi adingwa amasistimu alandelayo.

Njengoba umfanekiso ongezansi ubonisa, isilawuli esishintshayo singakha i-voltage ephumayo (V_PHUMA) ephakeme (isinyathelo-phezulu, i-boost), ephansi (isinyathelo-phansi, ibhendi) noma ene-polarity ehlukile kunaleyo ye-voltage yokufaka (V_IN)
Ukushintsha izici zesilawuli

Okulandelayo kunikeza incazelo yezici zesilawuli sokushintshwa ezingahlukanisiwe.

Ukusebenza kahle okuphezulu

Ngokuvula nokuvala into eshintshayo, isilawuli esishintshayo sinika amandla ukuguqulwa kukagesi osebenza kahle kakhulu njengoba sinikeza inani elidingekayo likagesi kuphela lapho kudingeka.
Isilawuli somugqa singolunye uhlobo lwesilawuli (ukunikezwa kwamandla okuzinzile), kodwa ngenxa yokuthi sichitha noma iyiphi imali enqwabelene njengokushisa enqubweni yokuguqula i-voltage phakathi kwe-VIN ne-VOUT, cishe asisebenzi kahle njengesilawuli esishintshayo.

Umsindo

Isici sokushintsha VULA/UKUVALE ukusebenza kusilawuli esishintshayo sidala izinguquko ezingazelelwe ku-voltage nezamanje, kanye nezingxenye ze-parasite ezikhiqiza ukukhala, zonke ezethula umsindo ku-voltage ophumayo.
Ukusebenzisa isakhiwo sebhodi esifanele kuphumelela ekudambiseni umsindo.Isibonelo, ukuthuthukisa ukubekwa kwe-capacitor ne-inductor kanye/noma izintambo.Ukuze uthole ulwazi olwengeziwe mayelana nendlela umsindo (ukukhala) okhiqizwa ngayo nokuthi ulawulwa kanjani, bheka Inothi Lokusebenza "Izinyathelo Zokulwa Nomsindo Wokushintsha Ukushintsha Okuya Phansi."
