Li-switching regulators ke mokhoa o sebetsang ka ho fetesisa oa ho fetolela motlakase o le mong oa DC ho o mong oa DC.'Me ho pholletsa le li-topology tsohle tsa DC/DC tseo e seng tse ikhethileng - buck, boost, buck-boost le inverting - re u thusa ho holisa ts'ebetso ea motlakase oa hau oa IC ka khetho e kholo ka ho fetisisa indastering ea li-converter tsa DC/DC, li-module tsa motlakase le li-controller.
Matla a matla
Matla a mangata, sebaka se senyenyane sa boto.E totobalitsoe ke lelapa la SWIFT ™ buck regulator, potefolio ea rona ea lisebelisoa tsa matla a phahameng a matla li kopantsoe haholo, li na le lisebelisoa tse sebetsang hantle haholo le bokhoni bo phahameng ba hona joale ba ho paka ka har'a komporo e ntlafalitsoeng ka mocheso.
Li-switching regulator tse phahameng haholo ke khetho e ntle ea ho matlafatsa meroalo ea morao-rao ea dijithale joalo ka li-FPGA le li-processor.Sebelisa sesebelisoa sa rona sa ho hokela processor ho fumana lihlahisoa tse ntle ka ho fetisisa tse tlatselletsang FPGA kapa processor ea hau.
EMI e tlase
Ho fokotsa switching regulator EMI e ka ba phephetso e kholo ho baqapi ba bangata ba phepelo ea motlakase.Lisebelisoa tse nang le mahlale a hahelletsoeng ka har'a EMI-phokotso li boloka nako ea moralo ha li ntse li u thusa ho latela maemo a thata joalo ka CISPR 25 Class-5.Sheba lihlahisoa tsa rona tse hlahang ka tlase bakeng sa tse ling tsa morao-rao le tse ntle ka ho fetisisa tsa li-switch tsa DC/DC bakeng sa ts'ebetso ea EMI.
Nako e tlase e khutsitseng (IQ)
Lilaoli tsa li-switching tsa DC/DC tse nang le matla a tlase a khutsitseng li eketsa katleho ea mojaro o bobebe le ho lelefatsa bophelo ba betri lits'ebetsong tse nkehang habonolo le tse tsamaisoang ke betri.Fumana tse ling tsa lisebelisoa tse tlase tsa IQ ho portfolio ea rona ea switcher ka tlase.
Lerata le tlase le ho nepahala
Li-switching regulators tse tloaelehileng li hloka LDO ea post-regulator ho matlafatsa li-ADC le li-AFE tse phahameng.Empa ka ts'ebetso e ntle ka ho fetisisa ea lerata le ts'ebetso ea ripple, TPS62912 le TPS62913 li u lumella ho tlosa LDO ea lerata le tlase lits'ebetsong tse ngata, ho boloka sebaka sa PCB le litšenyehelo ka kakaretso ha u ntse u ntlafatsa ts'ebetso ea sistimi.
