Siab zog ceev, ceev teb nqi-tswj switching fais fab mov tswj nti
SCM1725A nti yog hom kev ua haujlwm siab tam sim no PWM tswj nti, nti sab hauv kev sib xyaw ua ke qhov tsawg kawg nkaus tiv taus qhov hluav taws xob ntawm 650V 2A lub hwj chim raj, high-voltage pib tus pin los ntawm kev txuas ncaj qha mus rau lub zog hluav taws xob tsheb npav, kom ua tiav kev them nyiaj sai ntawm VDD bypass capacitor, nyob rau tib lub sij hawm, nyob rau hauv lub nti pib lub luv luv-circuit tiv thaiv, lub VDD capacitor voltage poob mus rau lub point uas VDD under-voltage, high-voltage ceev pib Circuit Court tib lub sij hawm, tom qab lub nti pib lub luv luv. kev tiv thaiv Circuit Court, VDD capacitor voltage poob mus rau VDD undervoltage point, high voltage fast start circuit restarts to charge the VDD bypass capacitor kom txog rau thaum nws mus txog VDD pib voltage, pib Circuit Court nres ua hauj lwm kom txo tau qhov poob.
Vim lub nti built-in lub teeb load zaus hopping hom, yog li ntawd nws muaj ib tug zoo heev efficiency ntawm lub teeb loads, tab sis kuj built-nyob rau hauv lub luag hauj lwm voj voog txoj kab nqes them, internal voj them nyiaj thiab lwm yam circuits, yog li ntawd lub voj voog ua haujlwm yog. ruaj khov dua. Txhawm rau txhim kho kev ntseeg tau ntawm lub cev, lub nti kuj tseem koom ua ke ntawm kev tiv thaiv sab hauv. Tsis tas li ntawd, cov nti ua ke nrog EN tus pin, sab nraud logic qib siab, tuaj yeem tswj cov nti rau hauv hom kev siv hluav taws xob tsawg, thiab tib lub sijhawm ua rau VDD tus pin voltage tswj ntawm li 8.6V voltage. Thaum lub nti muaj cov cua kub txaus, nyob rau hauv qhov qhib 75 degree ib puag ncig 3S rau / tawm kev ua haujlwm tsis sib xws, qhov siab tshaj plaws tso zis hluav taws xob mus txog 20W.
