♠ I-LM4991 3W Isikhulisi Samandla Omsindo esinemodi yokuvala shaqa
I-LM4991 iyi-mono bridged audio amplifier ekwazi ukuletha u-3W wamandla aqhubekayo ayisilinganiso kumthwalo ongu-3Ω ongaphansi kuka-10% THD uma inikwa amandla ukunikezwa kwamandla okungu-5V (bona Inothi ngezansi).Ukonga amandla ezinhlelweni eziphathwayo, imodi yokuvala amandla amancane ye-LM4991 (ISD = 0.1µA,typ) iyasebenza uma i-VDD isetshenziswa kuphinikhodi ethi SHUTDOWN.
Ama-amplifiers wamandla omsindo we-Boomer aklanyelwe ngqo ukunikeza amandla aphezulu, okukhiphayo komsindo okwethembeka okuphezulu.Zidinga izingxenye zangaphandle ezimbalwa futhi zisebenza ngama-voltage okunikezwayo aphansi ukusuka ku-2.2V ukuya ku-5.5V.Njengoba i-LM4991 ingadingi okukhiphayo ama-capacitor ahlanganisayo, ama-bootstrap capacitor, noma amanethiwekhi e-snubber, ifaneleka kahle kumasistimu aphathekayo anamandla aphansi adinga umthamo omncane kanye isisindo.
Izici ezengeziwe ze-LM4991 zifaka ukuvikela ukuvala shaqa okushisayo, ukuzinza kwenzuzo yobumbano, nesethi yenzuzo yangaphandle.
