4 회로설명 LinkSwitch-PH(U1) 는 LED 드라이버애플리케이션에서사용하도록설계된고집적 1 차측컨트롤러입니다. LinkSwitch-PH 는일반적인 LED 드라이버환경에서발생할수있는입력및출력전압조건에서의출력전류레귤레이션을일체형 (single-stage) 변환토폴로지에서실행하여높은역률을제공합니다. 이기능을제어하는모든컨트롤회로와고전압파워 MOSFET 이이디바이스에통합되어있습니다. 커패시터 C1, C2, 디퍼렌셜초크 L1, L2 및 L3 은 EMI 필터링을하며고역률을유지하도록크기가조정되었습니다. 저항 R1 과 R2 는 L1 과 L2 의 Q 를댐핑하여 EMI 스펙트럼에서공진피크를방지하는데사용됩니다. 플로우팅출력의벅 - 부스트전력회로는 U1( 파워스위치 + 컨트롤 ), 출력다이오드 D2, 출력커패시터 C7 및 C8, 출력인덕터 T1 로구성되어있습니다. 인덕터 T1 에는플라이백구성에서 U1 에바이어스전력을공급하도록구성된 2 차측권선이있습니다. 다이오드 D7 은입력전압이제로점아래까지떨어지는경우에도 U1 의드레인 - 소스간에마이너스전압이나타나지않도록하기위해사용되었습니다. 다이오드 D1 및 C3 은피크 AC 입력전압을감지합니다. R4 및 R5 와함께 C3 의전압은 VOLTAGE MONITOR(V) 핀에공급되는입력전류를설정합니다. 이전류는 U1 이입력저전압 (UV), 과전압 (OV) 및피드포워드전류를제어하는데사용하고이전류를 FEEDBACK(FB) 핀전류와함께사용하여 LED 부하에정전류를공급합니다. 출력전류레귤레이션용으로 U1 에사용되는 FB 핀전류는전압을전류로변환시키는네트워크 (R10, R11, R12, R13, Q1, C9 및 D5) 에의해공급됩니다. 출력전압과피드백전류의연관성은다음의공식에서확인할수있습니다. I FB I R13 V OUT R12 R11 R12 R13 V BE R12 의전압은, Q1 의 V BE 전압에따라달라지는 V CE 와온도의영향을없애거나최소화하기위해선택되었습니다. 커패시터 C4 은내장컨트롤러용서플라이핀에해당하는 U1 의 BYPASS(BP) 핀에로컬디커플링을제공합니다. 스타트업동안에 C4 은 U1 의 DRAIN(D) 핀에연결된내부고전압전류소스를통해 ~6V 로충전됩니다. 디바이스가최대모드에서작동하도록하기위해커패시터 C4 는 10 F 로설정했습니다. 딥디밍상태에서디바이스전력소모는최소로하고 U1 에효율적으로공급하기위해 D6 및 R8 을통해외부바이어스서플라이를사용했습니다. 출력과전압 ( 오픈부하 ) 보호는 V 핀과 VR1, R14 및 D3 을통해제공됩니다. 오픈부하상태로인해바이어스서플라이의커패시터 C6 에서전압이 VR1 기준값을 Page 8 of 48
초과한경우전류가 V 핀으로흐르고라인과전압기준값 (I OV ) 에도달하면출력전압이더이상오르지않도록 IC 스위칭이즉시종료됩니다. Page 9 of 48
