♠ TPS92692, TPS92692-Q1 Igenzura Ryinshi LED Igenzura hamwe na Spread Spectrum Frequency Modulation
TPS92692 na TPS92692-Q1 nukuri kwukuri kurwego rwo hejuru rushingiye kubigenewe byashizweho kugirango bishyigikire intambwe / hasi ya LED ya topologiya. Igikoresho kirimo gari ya moshi-gari ya moshi yongerera ingufu zapima LED ikwirakwiza no gukwirakwiza tekinoroji ya tekinoroji yo guhindura imikorere ya EMI.
Iyi mikorere yo hejuru LED igenzura irashobora kwigenga guhindura LED ikoresha ikoresheje uburyo bwa analog cyangwa PWM dimming. Umurongo wa analog dimming igisubizo hamwe hejuru ya 15: 1 haboneka muguhindura voltage kuruhande rwikigereranyo kinini cyo kugereranya (IADJ) ibyinjijwe. PWM dimming ya LED igerwaho muguhindura mu buryo butaziguye DIM / PWM yinjiza pin hamwe ninshingano zifuzwa cyangwa mugushoboza amashanyarazi ya PWM imbere. Imashini ya PWM isobanura voltage ya DC kuri pin ya DIM / PWM kumurongo ukurikirana ugereranije nu mashanyarazi ya triangle y'imbere. Ihitamo rya PDRV irembo rishobora gukoreshwa mugutwara P-Umuyoboro wo hanze MOSFET.
Ibikoresho bya TPS92692 na TPS92692-Q1 bishyigikira igenzura rya LED rihoraho binyuze muri monitor ya none (IMON). Ibikoresho kandi birimo gufungura imiyoboro yerekana imiyoboro yerekana ibyerekanwe na LED birenze, ibisohoka birenze urugero hamwe nibisohoka munsi ya volvoltage.
