Maorui Core rau hauv Philips cov saw hlau
Oct 19, 2022| Maorui Core rau hauv Philips cov saw hlau
schitec yav dhau los disassembled Philips 30W 1A1C gallium nitride charger, thiab pom tias nws cov thawj tswj nti siv cov tub ntxhais MK2697G, uas yog ib tug high-frequency QR AC-DC PWM tswj nti nrog SOT23-6 pob tsawg. Nws txhawb PPS cov zis ntau yam thiab muaj kev hloov pauv ntau hom yam ntxwv. Ua tau raws li qhov yuav tsum tau ua lub zog ntawm PD ceev them raws li qhov sib txawv ntawm cov zis voltages.
Maorui MK2697G Vcc tiv taus 110V, txhawb nqa 9-90V Vcc fais fab mov, tsis muaj hluav taws xob sab nraud regulator Circuit Court, txo qhov chaw ntawm lub rooj tsavxwm, siv tau yooj yim dua. Lub tshuab tsav tsheb patented txhawb nqa ncaj qha-tsav txhim kho GaN cov khoom siv hluav taws xob, thiab ua kom zoo dua SR Vds kev ntxhov siab, txhim kho cov khoom lag luam zoo thiab lub zog ntom ntom.
MK2697G txhawb nqa 200KHz kev khiav hauj lwm zaus, uas tuaj yeem ua kom zoo dua ntawm kev hloov pauv ntawm gallium nitride, txhim kho kev ua haujlwm thiab txo cov adapter loj. Lub nti muaj ntau yam kev tiv thaiv xws li tso zis overvoltage, overpower, VCC overvoltage, input overvoltage tiv thaiv thiab synchronous rectifier luv Circuit Court tiv thaiv. Nws yog tsim rau USB PD charger thiab siab zog ceev fais fab mov daim ntaub ntawv.
