♠ TPS54302 4.5-V a 28-V Hookomo, 3-A Puke, EMI-Friendly Synchronous Step-down Converter
ʻO ka hāmeʻa TPS54302 he 4.5-V a i ka 28-V input voltage range, 3-A synchronous buck converter. Loaʻa i ka hāmeʻa ʻelua FET hoʻololi i hoʻohui ʻia, ka loop loopuku, a me 5-ms hoʻomaka palupalu i loko e hōʻemi i ka helu ʻāpana.
Ma ka hoʻohui ʻana i nā MOSFET a me ka hoʻohana ʻana i ka pūʻolo SOT-23, loaʻa i ka hāmeʻa TPS54302 ka mana kiʻekiʻe a hāʻawi i kahi wāwae liʻiliʻi ma ka PCB.
ʻO ka hoʻokō Eco-mode kiʻekiʻe e hoʻonui i ka pono o ka ukana māmā a hoʻemi i ka nalowale o ka mana.
Ma ka polokalamu TPS54302, ua hoʻokomo ʻia ka hana hoʻolaha alapine no ka emi ʻana o EMI.
Mālama ʻia ka palena o ka pōʻaiapuni ma ka pōʻaiapuni i ka MOSFET ʻaoʻao kiʻekiʻe i ka mea hoʻololi i kahi kūlana kaumaha a hoʻonui ʻia e ka palena haʻahaʻa MOSFET freewheeling o kēia manawa e pale ai i ka holo ʻana o kēia manawa. Hoʻomaka ʻia ka pale ʻana i ke ʻano hiccup inā lōʻihi ke kūlana overcurrent ma mua o kēia manawa.
• 4.5-V a hiki i 28-V ākea ākea hoʻokomo uila
• Nā MOSFET 85-mΩ a me 40-mΩ i hoʻohui ʻia no 3-A, hoʻomau i ka hoʻopuka ʻana i kēia manawa.
