♠ TPS92692, TPS92692-Q1 Wowongolera Wolondola Kwambiri wa LED Wokhala ndi Kusinthasintha kwa Spectrum Frequency Modulation
Ma TPS92692 ndi TPS92692-Q1 ndiwowongolera olondola kwambiri pakali pano omwe amapangidwa kuti azithandizira kuwongolera / kutsika kwa madalaivala a LED.Chipangizochi chimaphatikizapo amplifier ya njanji-to-njanji kuti ayeze njira yamakono ya LED ndi kufalitsa ma frequency modulation njira kuti EMI igwire bwino.
Wowongolera wa LED uyu amatha kusinthira pompopompo pawokha pogwiritsa ntchito njira za analogi kapena PWM dimming.Mayankhidwe ocheperako a analogi okhala ndi mitundu yopitilira 15:1 amapezeka posintha ma voliyumu pamakina apamwamba kwambiri a analogi (IADJ).Kuthima kwa PWM kwa LED komweko kumatheka posintha mwachindunji pini yolowera ya DIM/PWM ndi ntchito yomwe mukufuna kapena pothandizira kuzungulira kwa jenereta ya PWM.Jenereta ya PWM imamasulira magetsi a DC pa pini ya DIM/PWM kupita ku ntchito yofananira poiyerekeza ndi jenereta yamkati yamakona atatu.Chosankha choyendetsa chipata cha PDRV chingagwiritsidwe ntchito kuyendetsa gulu lakunja la P-Channel MOSFET.
Zida za TPS92692 ndi TPS92692-Q1 zimathandizira kuyang'ana kwa mawonekedwe a LED mosalekeza kudzera pa chowunikira chapano (IMON).Zipangizozi zimaphatikizansopo chizindikiro chotseguka chowonetsera kukhetsa kwa LED kuwonetsa kuchulukirachulukira kwa LED, kuchulukirachulukira komanso kutsika kwamagetsi.
