♠ TPS61196-Q1 6-String 400-mA WLED Keaukaha me ka PWM Dimming kūʻokoʻa no kēlā me kēia kaula.
Hāʻawi ka TPS61196-Q1 i kahi hoʻonā i hoʻohui ʻia no ke kukui LCD automotive me kahi hana dimming PWM kūʻokoʻa no kēlā me kēia kaula. ʻO kēia hāmeʻa kahi mea hoʻokele hoʻoikaika mode i kēia manawa e hoʻokele ana i ʻeono mau kaula WLED me nā LED he nui i ka moʻo. Loaʻa i kēlā me kēia kaula kahi hoʻoponopono kūʻokoʻa kūʻokoʻa e hāʻawi ana i kahi LED i hiki ke hoʻololi ʻia mai 50 mA a i 400 mA i loko o ± 1.5% ka pololei kūpono. Hiki ke hoʻolālā ʻia ka liʻiliʻi liʻiliʻi o ka puʻu o kēia manawa ma ke ʻano o 0.3 V a i 1 V e kūpono me nā hoʻonohonoho LED ʻokoʻa. Mai ka 8 V a hiki i ka 30 V ka nui o ka volta hoʻokomo.
Hoʻoponopono ka TPS61196-Q1 i ka uila puka o ka mea hoʻoulu e hāʻawi wale i ka voltage i koi ʻia e ke kaula LED me ka hāʻule ʻana o ka uila mua nui a me ka haʻahaʻa haʻahaʻa i koi ʻia ma ka pine IFB o kēlā kaula, a laila e hoʻomaikaʻi i ka pono o ka mea hoʻokele. Hoʻonohonoho ʻia kona alapine hoʻololi e kahi resistor waho mai 100 kHz a i 800 kHz.
Kākoʻo ka TPS61196-Q1 i ka hoʻolohilohi PWM pololei. Loaʻa i kēlā me kēia kaula kahi hoʻokomo mana PWM kūʻokoʻa. I ka wā o ka PWM dimming, ua ho'ā a ho'opau 'ia ke ala LED ma ke alapine a me ka pō'ai hana i ho'oholo 'ia e ka hō'ailona PWM waho. ʻO ke alapine PWM mai 90 Hz a 22 kHz.
Hoʻohui ka TPS61196-Q1 i ka pale o ka overcurrent, ka pale ʻana i ka pōkole pōkole, ka pale ʻana o ka ISET pōkole, ka diode wehe a me ka pale pōkole, LED hāmama a pōkole, a me ka overtemperature shutdown circuit. Eia kekahi, hiki i ka TPS61196-Q1 ke ʻike i ka pin IFB pōkole i ka honua e pale i ke kaula LED. Hāʻawi ka hāmeʻa i ka paepae hoʻokomo undervoltage laka a me ka paepae pale overvoltage puka.
