♠ TPS5433xA 4.5-V a i 28-V Hookomo, 3-A Puke, Hoʻololi i lalo DC-DC Hoʻohui

ʻO ka ʻohana TPS5433xA o nā polokalamu he mau mea hoʻololi synchronous me kahi kikowaena-voltage o 4.5 V a hiki i 28 V. Aia kēia mau mea i kēia mea he FET hoʻololi haʻahaʻa i hoʻohui ʻia e hoʻopau i ka pono o kahi diode waho e hōʻemi ana i ka helu ʻāpana.

Hoʻonui ʻia ka maikaʻi ma o nā MOSFET 128-mΩ a me 84-mΩ MOSFET, haʻahaʻa IQ a me ka lele ʻana o ka pulse ma nā haʻahaʻa māmā.Me ka hoʻohana ʻana i ka pin hiki, ua hoʻemi ʻia ka manawa pani pani i 2 μA.Hāʻawi kēia mea hoʻololi i lalo (buck) i ka hoʻoponopono pololei no nā ʻano haʻahaʻa like ʻole me kahi kuhikuhi uila i hoʻoponopono maikaʻi ʻia ʻo 1.5% ma luna o ka mahana.

Mālama ʻia ke kaʻina holoʻokoʻa i kēia manawa ma ka MOSFET ʻaoʻao kiʻekiʻe i ka ʻohana TPS5433xA o nā mea hana i nā kūlana overload a hoʻonui ʻia e ka palena haʻahaʻa loaʻa i kēia manawa e pale ai i ka holo ʻana o kēia manawa.Hoʻopau ka palena haʻahaʻa hāʻule i ka MOSFET ʻaoʻao haʻahaʻa no ka pale ʻana i ka nui o ke au hope.Hoʻomaka ka pale ʻana i ka hiccup inā hoʻomau ke kūlana overcurrent no ka lōʻihi o ka manawa i hoʻonohonoho ʻia.Hoʻopau ka wela wela i ka hāmeʻa ke ʻoi aku ka wela o ka make ma mua o ka paepae a hiki ke hoʻi hou i ka hāmeʻa ma hope o ka manawa hiccup thermal i kūkulu ʻia.
