Hloov Regulators
Switching regulators yog ib hom Circuit Court uas muaj peev xwm hloov hluav taws xob thiab cov tswv yim tam sim no rau hauv qhov hluav taws xob thiab cov zis tam sim no uas tsim nyog tshaj plaws rau lub zog uas nws tsim lub zog rau.Cov hom circuits no tseem hu ua converters thiab yog qhov zoo tshaj plaws rau kev tswj lub zog uas hloov ntawm ob lub ntsiab lus sib txuas kom tswj tau qhov hluav taws xob tsis tu ncua uas muaj kev nyab xeeb nyob rau hauv qhov txwv ntawm Circuit Court.Lawv ua hauj lwm ntawm ib tug ntau dua conversion efficiency dualinear regulatorsthiab muab cov txiaj ntsig zoo ntawm kev tswj xyuas hluav taws xob zoo dua thiab muaj txiaj ntsig zoo nyob rau lub sijhawm ntev, nrog rau qhov tseeb tias lawv feem ntau tsis tas yuav muaj cov khoom siv hluav taws xob sab nraud.
Dab tsi yog switching regulators siv rau?
Cov hom kev tswj hwm no feem ntau yog siv rau ib leeg lossis ntau lub xov tooj ntawm cov roj teeb uas siv tau thiab rau cov khoom siv hluav taws xob siv hluav taws xob xws li cov koob yees duab digital, handheld games consoles, controllers thiab ntau dua.Qhov txiaj ntsig tseem ceeb ntawm kev siv cov kev hloov pauv hloov pauv hloov cov kab hluav taws xob yog tias lawv muaj kev tiv thaiv luv luv thiab ua kom muaj kev tiv thaiv dhau-voltage thiab qis-voltage.Lawv kuj yog qhov zoo rau kev tiv thaiv hluav taws xob los ntawm kev kub dhau thiab kev puas tsuaj ntau dhau.
Hom kev hloov regulators
Kauj ruam-Up lossis Boost Regulators - Cov no yog hom yooj yim tshaj plaws ntawm kev hloov regulator thiab yog siv los ua kom cov zis voltage.
· Cov kauj ruam-Down lossis Buck-Boost Converters - Lawv txo lossis thim rov qab cov zis hluav taws xob nrog rau qhov input voltage

Nqe lus piav qhia rau LP87524J-Q1
LP87524B/J/P-Q1 yog tsim los ua kom tau raws li kev tswj hwm lub zog ntawm cov txheej txheem tshiab thiab cov platforms hauv ntau daim ntawv thov hluav taws xob tsheb.Cov cuab yeej muaj plaub kauj ruam-down DC-DC converter cores, uas tau teeb tsa raws li 4 theem ib theem tawm.Cov cuab yeej yog tswj los ntawm ib qho I2C-tshaj serial interface thiab pab kom cov teeb liab.
Kev ua haujlwm tsis siv neeg PFM / PWM (AUTO hom) ua haujlwm kom ua tau zoo tshaj qhov kev tso tawm dav dav-tam sim no ntau yam.LP87524B/J/P-Q1 txhawb nqa tej thaj chaw deb voltage sensing los them IR poob ntawm tus regulator tso zis thiab lub point-of-load (POL) yog li txhim kho qhov tseeb ntawm cov zis voltage.Tsis tas li ntawd, lub moos hloov pauv tuaj yeem raug yuam mus rau PWM hom thiab tseem synchronized rau lub moos sab nraud kom txo qis kev cuam tshuam.
LP87524B/J/P-Q1 ntaus ntawv txhawb nqa load-tam sim no ntsuas yam tsis muaj qhov sib ntxiv ntawm sab nraud tam sim no-sensors.Tsis tas li ntawd, LP87524B/J/P-Q1 txhawb nqa programmable pib-up thiab kaw qeeb thiab sib txuas ua ke kom pab tau cov teeb liab.Cov kab ke kuj tseem tuaj yeem suav nrog GPIO cov teeb liab los tswj cov kev tswj hwm sab nraud, hloov pauv thiab cov txheej txheem rov pib dua.Thaum pib thiab hloov hluav taws xob, lub cuab yeej tswj hwm qhov tso tawm slew tus nqi kom txo qis cov zis hluav taws xob overshoot thiab qhov nrawm tam sim no.
