Power Management Chip IC ke setsi sa phepelo ea motlakase le sehokelo sa lihlahisoa le lisebelisoa tsohle tsa elektroniki, tse ikarabellang bakeng sa phetoho, kabo, ho lemoha le mesebetsi e meng ea taolo ea matla a hlokahalang, ke sesebelisoa sa bohlokoa sa bohlokoa sa lihlahisoa le lisebelisoa tsa elektroniki.Ka nako e ts'oanang, ka nts'etsopele ea Marang-rang a Lintho, matla a macha, bohlale ba maiketsetso, liroboto le likarolo tse ling tse ntseng li hlaha tsa kopo, 'maraka o tlase oa li-chips tsa taolo ea matla o ile oa kenya menyetla e mecha ea nts'etsopele.Se latelang ke ho hlahisa karohano, ts'ebeliso le kahlolo ea taolo ea matla litsebo tse amanang le IC chip.
Tlhophiso ea chip ea taolo ea matla
Karolo e 'ngoe ka lebaka la ho ata ha li-ics tsa tsamaiso ea matla, li-semiconductors tsa matla li ile tsa rehoa li-semiconductors tsa tsamaiso ea matla.Ke hantle hobane lipotoloho tse ngata tse kopaneng (IC) lebaleng la phepelo ea motlakase, batho ba lebile taolong ea motlakase ho bitsa mohato oa hajoale oa theknoloji ea phepelo ea motlakase.Semiconductor ea taolo ea matla karolong e ka pele ea IC ea taolo ea matla, e ka akaretsoa joalo ka tse latelang 8.
1. AC / DC modulation IC.E na le potoloho e tlase ea taolo ea motlakase le transistor e phahameng ea motlakase.
2. DC / DC modulation IC.E kenyelletsa balaoli ba boost/step-down, le lipompo tsa ho tjhaja.
3. taolo ea matla a matla a PFC a ipapisitse le IC.Fana ka potoloho ea motlakase e nang le tšebetso ea tokiso ea lintlha tsa matla.
4. pulse modulation kapa pulse amplitude modulation PWM/ PFM taolo IC.Selaoli sa ho feto-fetoha ha lebelo la pulse frequency le/kapa pulse wide modulation bakeng sa ho khanna li-switches tsa kantle.
5. linear modulation IC (tse kang linear low voltage regulator LDO, joalo-joalo).E kenyelletsa balaoli ba pele le ba fosahetseng, le li-tubes tsa modulation tsa LDO tse tlase tsa voltage.
6. ho tjhaja le ho laola betri IC.Tsena li kenyelletsa ho tjhaja betri, tshireletso le di-ics tsa pontsho ya matla, mmoho le di-ics tsa "smart" tsa betri bakeng sa puisano ya data ya betri.
7. Hot swap board control IC (ho lokoloha tšusumetsong ea ho kenya kapa ho tlosa sebopeho se seng ho tloha tsamaisong ea ho sebetsa).
8. MOSFET kapa IGBT switjha tshebetso IC.
Har'a li-ics tsena tsa taolo ea matla, taolo ea motlakase ICS ke eona e holang ka potlako le e hlahisang litholoana haholo.Li-ics tse fapaneng tsa taolo ea matla hangata li amahanngoa le lits'ebetso tse 'maloa tse amanang, kahoo mefuta e mengata ea lisebelisoa e ka thathamisoa bakeng sa lits'ebetso tse fapaneng.
Ea bobeli, ts'ebeliso ea chip ea taolo ea matla
Sebaka sa taolo ea matla se batla se pharaletse, ha se akarelletse feela phetolo ea motlakase e ikemetseng (haholo-holo DC ho ea ho DC, e leng DC/DC), kabo e ikemetseng ea matla le ho lemoha, empa hape le phetolo e kopaneng ea matla le sistimi ea taolo ea matla.Ka hona, sehlopha sa chip ea taolo ea matla se kenyelletsa lintlha tsena, joalo ka linear power chip, voltage reference chip, switching power chip, LCD driver chip, LED driver chip, voltage discovery chip, chip ea taolo ea betri joalo-joalo.
Haeba moralo oa potoloho bakeng sa phepelo ea motlakase le lerata le phahameng le ripple khatello, o ile a kōpa ho nka sebaka se senyenyane PCB (mohlala, liselefouno le lihlahisoa tse ling tsa elektronike handheld), phepelo ea motlakase potoloho ha ba lumelloe ho sebelisa inductor (tse kang selefouno). , matla a nakoana a ho lekanya le ho hlahisa matla a ho itlhahloba e lokela ho ba mosebetsi oa ho itlhahloba, ho theoha ha khatello ho hlokehang ho matlafatsoa ha motlakase le tšebeliso ea eona e tlaase ea matla, mohala oa theko e tlaase le tharollo e bonolo, Ebe matla a motlakase ke khetho e nepahetseng ka ho fetisisa.Phepelo ena ea motlakase e kenyelletsa mahlale a latelang: referense e nepahetseng ea motlakase, ts'ebetso e phahameng, amplifier ea ts'ebetso ea lerata le tlase, regulator ea ho theoha ha motlakase o tlase, boemo bo tlase bo tsitsitseng.
Ntle le chip ea mantlha ea phetoho ea matla, chip ea taolo ea matla e boetse e kenyelletsa chip ea taolo ea matla ka sepheo sa tšebeliso e nepahetseng ea matla.Tse kang NiH battery intelligent quick charger chip, lithium ion battery charge and discharge management chip, lithium ion battery over voltage, over current, over the temperature, short circuit protection chip;Moleng oa phepelo ea matla le bekapo ea taolo ea betri switching chip, chip ea taolo ea matla a USB;Pompo ea ho tjhaja, phepelo ea motlakase ea LDO e nang le liteishene tse ngata, taolo ea tatellano ea matla, ts'ireletso e mengata, tefiso ea betri le chip e rarahaneng ea taolo ea matla, joalo-joalo.
Haholo-holo ho lisebelisoa tsa elektronike tsa bareki.Ka mohlala, e nkehang habobebe DVD, selefouno, khamera dijethale le joalo-joalo, hoo e ka bang ka 1-2 likotoana tsa matla a taolo ya chip ka fana ka rarahaneng mekhoa e mengata ea phepelo ea matla, e le hore tshebetso ya tsamaiso ho molemo ka ho fetisisa.
