INkcazelo yeziBonelelo zoNxibelelwano I-TPS54620 kwi-thermal ephuculweyo nge-3.50 mm ×
Iphakheji ye-3.50 mm ye-QFN yi-17-V, i-6-A, i-synchronous, i-step-down converter elungiselelwe ukuyila okuncinci ngobuchule obuphezulu kunye nokudibanisa i-MOSFETs yecala eliphezulu kunye necala eliphantsi. ulawulo lwemowudi, olunciphisa ukubalwa kwecandelo, kwaye ngokukhetha i-frequency switching frequency, ukunciphisa unyawo lwe-inductor.Irempu yokuqalisa umbane wokuphuma ilawulwa yi-SS/TR pin evumela ukusebenza njengombane ozimeleyo okanye ekulandeleni. iimeko.Ulandelelwano lwamandla lunokwenzeka ngokuqwalasela ngokuchanekileyo i-ivumela kunye ne-open-drain power pins elungileyo.Umyinge we-Cycle-by-cycle yangoku kwi-FET ekwicala eliphezulu ikhusela isixhobo kwiimeko ezigcwele kakhulu kwaye iphuculwe ngumda okhoyo wokukhangela osezantsi othintela ukubaleka kwangoku.Kukwakho necala elisezantsi lokuzikisa umda wangoku ocima i-MOSFET ekwicala elisezantsi ukunqanda umva ngokugqithisileyo wangoku.Ukuvalwa kwe-Thermal kuyenza ingasebenzi indawo xa ubushushu bokufa bugqitha ubushushu bokuvalwa kwe-thermal.
