Gulu la zida za TPS9260x-Q1 ndi njira imodzi yokha komanso yapawiri-mbali-yamakono ya LED
dalaivala.Ndi chitetezo chokwanira ndi diagnostics, gulu ili la zipangizo anapatulira ndi moyenera n'koyenera kwa magalimoto kutsogolo kuyatsa.Pansi pa dalaivala aliyense wodziyimira pawokha ndi chowongolera chapamwamba-panopa.Woyang'anira aliyense ali ndi malupu awiri odziyimira pawokha, loopu yaposachedwa yokhala ndi shunt yapamtunda wapakatikati komanso loopu ya voltage-feedback yokhala ndi netiweki yakunja ya resistor-divider.Wowongolera amapereka mphamvu yotulutsa nthawi zonse kapena aconstant output current.Katundu wolumikizidwa umatsimikizira ngati chipangizocho chimayang'anira kutulutsa kosalekeza (ngati dera likufika pamalo omwe akhazikitsidwa kale kuposa ma voltage set-point) kapena voteji yosalekeza (ngati dera likufika pagawo lamagetsi limafikira poyamba, mwachitsanzo, poyera. -load condition).Wowongolera aliyense amathandizira ma topology onse monga asboost, boost-to-battery, SEPIC, kapena flyback.Magwiritsidwe amtundu wapamwamba wa PMOS FET driver ndi a PWM dimming ya chingwe cha LED komanso kudula ngati kuli kofupika kunja. dera kupita ku GND kuteteza dera.Chidziwitso cha Chipangizo(1)PART NUMBER SENSE-VOLTAGE
