DER-328 10 W A19 Dimmable Buck LED Driver Using LNK460KG 07-Nov-12 3 회로설명 LinkSwitch-PL(U1) 제품군은 LED 드라이버애플리케이션에사용하도록설계된고집적파워 IC 입니다. LinkSwitch-PL 은일체형 (single-stage) 토폴로지에서고역률출력전류레귤레이션을제공합니다. 이기능을제어하는모든컨트롤회로와고전압파워 MOSFET 이본 IC 에통합되어있습니다. 3.1 입력단 퓨즈 FR1 은부품불량발생시보호기능을제공합니다. 디퍼렌셜라인서지중에는최대입력전압이 RV1 에의해클램핑됩니다. AC 입력은 U1 에흐르는스위칭전류에대한디커플링을제공하는 C6 과 BR1 에의해정류된전파입니다. 커패시터 C4, C11 과디퍼렌셜초크 L1 및 L3 은 EMI 필터를구성합니다. 높은역률을유지하기위해필터커패시턴스가제한됩니다. 입력다중 L 필터네트워크와 LinkSwitch- PL 의주파수지터링기능을통해클래스 B 노이즈규정을준수할수있습니다. 저항 R4 및 R9 는필요시 EMI 필터의공진점을댐핑하고시스템 ( 드라이버 + 인클로저 ) 에서측정할경우 EMI 스펙트럼에서피크를방지합니다. 3.2 LinkSwitch-PL 디바이스를사용한벅토폴로지 벅파워트레인은 U1( 파워스위치 + 컨트롤 ), D3( 프리휠링다이오드 ), C5 및 C9( 출력커패시터 ), T1( 인덕터 ) 로구성되어있습니다. 다이오드 D2 는스위치오프타임중 U1 의전압이그라운드아래에서링잉되는경우전위전류가역류하지않도록이를차단합니다. 바이패스커패시터 C1 은 U1 에전압을공급하고처음에는스타트업시 IC 의내부공급원을통해충전됩니다. C1 은효율을높이는데는물론딥디밍작동을수행하는데에도중요한역할을하며, 정류기 D1 및 D5 와평활커패시터 C10 을통해충전된상태로유지됩니다. 다이오드 D4 는스타트업시 C10 이로드되지않도록하는데사용되며 R1 은 BYPASS(BP) 핀으로흘러들어가는전류를제한합니다. 3.3 출력전류피드백 출력전류는저항 R6/R7 을통해간접적으로센싱되며센싱저항전체에나타나는신호는실제로스위치오프타임에발생하는인덕터전류입니다. 이전류는정상동작시평균 FEEDBACK(FB) 핀전압 290mV 를얻도록로우패스필터 (R3 및 C2) 를통해필터링됩니다. 바이패스커패시터 C3 은 R6/R7 에서전력소모를줄여효율을높이는데사용됩니다. 3.4 부하차단보호기능 드라이버는무부하동작시 VR1 을통해보호됩니다. 제너다이오드 VR1 은출력전압이 VR1 의애벌란치기준값을초과할경우단락됩니다. 이를통해 U1 이오토 - 리스타트 Power Integrations, Inc. Page 8 of 34

07-Nov-12 DER-328 10 W A19 Dimmable Buck LED Driver Using LNK460KG 모드로전환되며입력에서전력을과도하게끌어오지않게됩니다. 또한부하가차단될경우이러한동작을통해회로가보호됩니다. 3.5 과부하및단락보호 LinkSwitch-PL U1 은통합된전류제한보호기능을통해과부하와회로단락으로부터보호합니다. 단락이발생하면 1 차측전류가전류한도에도달하여 IC 가오토 - 리스타트모드로강제로전환될때까지축적됩니다. 3.6 패시브 RRCD 블리더및댐퍼 저항 R10, R11 및 C11 은블리더네트워크를형성하는데, 블리더네트워크는특히딥디밍시 (TRIAC 도통각이작을때 ) TRIAC 래칭및유지전류요구사항을충족할만큼초기입력전류를충분히높게유지하는역할을합니다. FR1 및 FR2 의총네트워크저항은댐핑동작을통해 TRIAC 가 ON 상태가될때마다입력전류를네거티브링잉으로부터보호합니다. 3.7 라인서지보호 MOV RV1 은서지이벤트발생시 IC 파워 MOSFET 의최대드레인전압보다낮게입력전압을클램핑합니다. Page 9 of 34 Power Integrations
