nkowa nkenke:

Ngwa TPS7B69xx-Q1 bụ onye na-ahụ maka usoro ahịrị dị ala nke emebere maka ihe ruru 40-VV._Iarụmọrụ.Na naanị 15-µA (nke a na-ahụkarị) quiescent ugbu a na ibu ọkụ, ngwaọrụ a dabara adaba maka sistemu microcontroller na-echere ọkachasị na ngwa ụgbọ ala.

Ngwa ndị a nwere ihe nchekwa mkpirisi mkpirisi agbakwunyere na ihe nchebe karịrị akarị.Ngwa TPS7B69xx-Q1 na-arụ ọrụ n'elu ogo -40°C ruo 125°C.N'ihi njirimara ndị a, ngwaọrụ TPS7B6925-Q1, TPS7B6933-Q1 na TPS7B6950-Q1 dabara nke ọma na akụrụngwa ọkụ maka ngwa ụgbọ ala dị iche iche.

N'ime ụwa nke akụrụngwa eletrọnịkị, onye na-achịkwa voltaji bụ otu n'ime ihe a na-ejikarị eme ihe, mana gịnị ka IC a na-eme?Ọ na-enye sekit nwere voltaji a na-ahụ anya na nke edobere oge niile, n'agbanyeghị voltaji ntinye.

Otu onye na-achịkwa voltaji si arụ ọrụ a bụ n'ikpeazụ onye nrụpụta.Enwere ike ijikwa ụfọdụ voltaji site na diode Zener dị mfe, ebe ngwa ndị ọzọ chọrọ topology dị elu nke linear ma ọ bụ mgbanwe mgbanwe.Na njedebe nke ụbọchị ahụ, onye na-achịkwa voltaji ọ bụla nwere ebumnuche mbụ na nke abụọ:

Nke mbụ:Iji mepụta voltaji mmepụta nke sekit na-azaghachi na mgbanwe dị na ọnọdụ voltaji ntinye.Ị nwere ike ịnwe 9V n'ime, ma ọ bụrụ na ị chọrọ naanị 5V, mgbe ahụ ị ga-mkpa agbada ya ala (Buck) na voltaji regulator.

Secondary: Ndị na-ahụ maka voltaji na-arụkwa ọrụ iji chebe ma chebe sekit eletrọnịkị gị site na mmebi ọ bụla nwere ike imebi.Ihe ikpeazụ ịchọrọ bụ ighe microcontroller gị n'ihi na ọ nweghị ike ijikwa mkpọ na voltaji.

Mgbe a bịara n'ịgbakwunye voltaji regulator na sekit gị, ị ga-arụ ọrụ na otu n'ime ụdị abụọ - Linear Voltage Regulators ma ọ bụ Switching voltaji Regulators.Ka anyị hụ otú ha abụọ si arụ ọrụ.
