♠ PWM Doubler nrog Cov Khoom Siv Saib Xyuas Cov Khoom
ISL6617A siv Intersil's proprietary Phase Doubler scheme los hloov ob-theem fais fab tsheb ciav hlau nrog ib qho PWM input. Nws ua ob npaug ntawm cov theem uas 3.3V multiphase controllers tuaj yeem txhawb nqa.
Lub ISL6617A yog tsim los txo tus naj npawb ntawm cov teeb liab analog uas cuam tshuam ntawm tus maub los thiab cov tsav tsheb hauv qib siab suav cov ntawv siv tau. Lub teeb liab COMP, uas feem ntau pom nyob rau hauv cov pa cascaded configurations, tsis tas yuav tsum tau; qhov no txhim kho lub suab nrov tiv thaiv thiab ua kom yooj yim rau kev teeb tsa. Tsis tas li ntawd, ISL6617A muab qhov suav tsawg thiab tus nqi qis dua li cov txheej txheem cascaded.
Los ntawm cascading ISL6617A nrog lwm ISL6617 lossis ISL6611A, nws tuaj yeem ua plaub npaug ntawm cov theem uas 3.3V multiphase controllers tuaj yeem txhawb nqa.
ISL6617A kuj tseem muaj cov khoom siv tri-state inputs thiab outputs uas paub txog lub xeev siab impedance, ua haujlwm ua ke nrog Intersil multiphase PWM controllers thiab cov theem tsav tsheb kom tsis txhob muaj qhov tsis zoo ntawm cov hluav taws xob tso tawm hluav taws xob thaum ua haujlwm raug ncua. Cov yam ntxwv no tshem tawm qhov xav tau ntawm Schottky diode uas tuaj yeem siv rau hauv lub zog hluav taws xob los tiv thaiv lub nra ntawm qhov tsis zoo ntawm cov zis hluav taws xob ntau dhau.
