27-Feb-14 DER-395 14.3 W PAR30 HLO Dimmable LED Driver Using LYT4322E 4 회로설명 LYT4322E(U1) 는 LED 드라이버애플리케이션에서사용하도록설계된고집적 1 차측컨트롤러입니다. 이컨트롤러는일체형변환단계에서입력범위 (195VAC~265VAC) 의출력전류를레귤레이션하면서동시에고역률을제공합니다. 이기능을제어하는모든컨트롤회로와고전압파워 MOSFET 가 IC 에통합되어있습니다. 4.1 입력 EMI 필터링퓨즈 F1은부품이고장나지않도록보호하고 RV1은라인서지중에최대전압을제한하도록클램핑합니다. 브릿지정류기 BR1은 AC 입력전압을정류합니다. 인덕터 L1, L2 와커패시터 C6, C7, C13 은 EMI 필터링을제공합니다. L1 및 L2 의저항 R10 과 R11 은해당공진주파수에서의전도성 EMI 플롯의노이즈피크를방지하기위해인덕터의자기공진을댐핑합니다. 선택된인덕터는자기차폐되어있지않고서로인접하여직렬로연결됩니다. 일관된 EMI 성능을내기위해 L1 과 L2 사이의자기커플링효과가레이아웃에신중하게고려되었습니다. 이설계에서 L1 는 L2 에수직으로장착되며권선의시작과끝이제어되며회로도와 PCB 에서도트로표시됩니다. ( 시작및끝권선에대한자세한내용은인덕터제조사데이터시트를참조하십시오.) 4.2 전력회로이설계에서선택한토폴로지는 195VAC~265VAC 의입력전압범위에서고역률및정전류출력을제공하도록구성된로우사이드탭벅입니다. 탭벅컨버터는트랜스포머소형화, 메인스위치 U1 의전류스트레스감소, 출력다이오드 D7 의전압스트레스감소와같은장점을제공합니다. 메인스위치의전류스트레스가줄어들면더작은스위칭디바이스를사용할수있어비용효율적으로설계할수있습니다. 인덕터 T2 은벅컨버터의메인인덕터이며, 1 차측, 2 차측및바이어스로구성되어있습니다. U1 LYT4322E 의최대전압을최대값아래로낮게잘유지하면서 300 V 출력다이오드를사용할수있도록 1 차측대 2 차측비율을 3:1 로선택했습니다. U1 이 OFF 상태일때마다출력다이오드 D7 이작동하여부하에에너지를전달합니다. C7 의전압 ( 정류된입력 AC) 이출력전압이하로떨어질때역방향전류가 U1 을통해흐르는것을방지하기위해다이오드 D5 이필요합니다. 또한 T2 의누설인덕턴스에의해생성되는전압스파이크를제한하기위해서전압클램프회로가추가되었습니다. 전압클램프네트워크는다이오드 D4, 커패시터 C9, 저항 R15 및 R16 로구성됩니다. 출력리플을최소화하기위해 (<30%) 출력커패시터 C12 가선택되었습니다. 더미부하저항 R24 및 R25 는 AC 가제거될때출력이 LED 스트링전압아래로빠르게방전되도록 Page 9 of 51

DER-395 14.3 W PAR30 HLO Dimmable LED Driver Using LYT4322E 27.02.14 하여램프가 AC 가제거된뒤몇초동안약하게빛나는현상없이완전히꺼지게해줍니다. 들어오는정류된 AC 피크는피크입력전압정보를 U1 에제공하기위해 D3 을통해 C8 을충전합니다. 그런다음 R13 및 R14 를통해 U1 의 VOLTAGE MONITOR(V) 핀에전류로공급됩니다. 더정밀한라인 / 부하레귤레이션을제공하기위해 R27 이추가되었습니다. 저항 R12 는들어오는 AC 의변경을추적할수있도록 C8 의양단전압에대한방전경로를제공합니다. 입력과전압셧다운기능 (V 핀전류를통해센싱 ) 은정류된입력전압내성 ( 서지및입력팽창시 ) 을내부파워 MOSFET 의 725BV DSS 정격으로확장합니다. 커패시터 C10 는내장컨트롤러용서플라이핀에해당하는 U1 의 BYPASS(BP) 핀에로컬디커플링을제공합니다. 스타트업동안에 C10 는 U1 의 DRAIN(D) 핀에연결된내부고전압전류소스를통해 6V 까지충전됩니다. 디바이스가최대모드에서작동하도록하기위해커패시터 C10 는 4.7µF 로설정했습니다. U1 의 REFERENCE(R) 핀은저항 R17 을통해그라운드 (SOURCE) 에연결됩니다. 정밀한 CC 레귤레이션을제공하기위해 24.9kΩ 값이사용됩니다. 4.3 바이어스전압및출력피드백 T2 의바이어스권선은피드백을제공하고 IC 에전류를공급하는데사용됩니다. 이바이어스권선의플라이백전압은 D8 에의해정류되고 C11 에의해평활되며, R20 은누설인덕턴스에너지에의해커플링되는과도한전압을줄이는역할을합니다. 계속해서피드백전류는저항 R18 를통해 FEEDBACK(FB) 핀으로공급됩니다. 다이오드 D9 와 R19 가 BP 핀을바이어스권선에연결합니다. 다이오드 D9 은스타트업동안 C10 을 C11 과분리하는데사용되고, 저항 R19 은바이어스권선에서 BP 핀으로공급되는전류를제한합니다. 저항 R21 은바이어스전압에부하를제공하여 AC 사이클동안 C11 의방전을촉진하고더높은디밍비율달성을돕습니다. 4.4 TRIAC 위상디밍컨트롤호환성 TRIAC 을기반으로하는낮은가격의리딩엣지및트레일링엣지위상디머를사용하여출력디밍을제공하기위해다양한균형방안이설계에적용되었습니다. LED 기반조명이기존의백열등전구와비교해훨씬낮은전력을소비하므로램프가끌어오는전류는디머내에있는 TRIAC 의유지전류아래로떨어질수있습니다. 이로인해 TRIAC 이불규칙적인작동을할때제한된디밍범위및 / 또는깜박임과같은바람직하지않은동작이발생합니다. LED 램프가라인에제공하는상대적으로큰임피던스덕분에 TRIAC 이 ON 상태일때입력커패시턴스를충전하는돌입전류로인해링잉이크게발생할수있습니다. 또한이경우링잉으로인해 TRIAC 전류가 0 으로내려가거나 TRIAC 이 OFF 상태가되는등의바람직하지않은동작이일어날수있습니다., Inc. Page 10 of 51

27-Feb-14 DER-395 14.3 W PAR30 HLO Dimmable LED Driver Using LYT4322E 설계에적용된댐퍼, 블리더및선형레귤레이터회로는드라이버의효율성에미치는영향을최소화하면서이러한문제를해결합니다. 저항 R2 및 R8 은패시브댐핑을제공합니다. 패시브블리더네트워크는커패시터 C1 과 R1//R26 으로구성됩니다. 이네트워크는입력네트워크을댐핑하고 TRIAC 디머에필요한래칭및유지전류를제공합니다. IC 가매우낮은도통각이나매우낮은입력전압에서도정상적으로작동하고특히누설전류가높은 TRIAC 에필수적인부하로동작할수있도록 IC 서플라이 (BP 핀 ) 를일정하게유지하기위해선형레귤레이터회로 R22, R23, VR2, Q3 및 D10 이추가되었습니다. 대부분의고전력정격 (600W 초과 ) TRIAC 디머에는 LC 입력필터가있습니다. RC 의커패시턴스의크기가커서 LED 드라이버의입력단을충전할수있을만큼충분한에너지를제공하는경우입력이방전될때까지 LED 부하에에너지가공급되므로 LED 를켤수있습니다. 계속해서이사이클이반복되면 TRIAC 이 OFF 상태인경우에도 LED 부하가깜박이게됩니다. 바이어스전압이 Vz VR2 +Vt Q3 +Vf D10 보다높은경우선형레귤레이터가활성화되지않습니다. 바이어스전압이매우낮은경우선형레귤레이터가딥디밍동안에만작동하도록전압레귤레이터 VR2 가사용되며, 이를통해 Q3 전력소모를최소화할수있습니다. Q3 는저비용 BJT(400V) 를사용하며저항 R22 및 R23 은딥디밍상태에서입력전압이낮을때도충분한드라이브를제공합니다. Page 11 of 51

DER-395 14.3 W PAR30 HLO Dimmable LED Driver Using LYT4322E 27.02.14 16.2 회로설명 Resistors R2 and R8 provide passive damping and the surrounding circuit comprised of D1, R6, R7, C3, VR1, C4, Q2, and R9 minimize power dissipation of R2 and R8 by operating Q2 in linear mode approximately 2 ms after the TRIAC turns ON. Capacitor C2, R3, R4, R5 and Q1 provide a discharge path so that Q2 is initially turned OFF when the next TRIAC switching cycle begins. The values were also selected such that when there is no TRIAC connected, Q2 will be permanently ON which helps improve efficiency in non-dimming operation. With this circuit, the values of R2 and R8 can be increased further for better dimmer compatibility but with less impact on the thermal performance of these resistors during dimming. 16.3 효율성데이터 With the active damper circuit, efficiency improves by as much as +2% over the one without the optional circuit. 16.3.1 댐퍼없음 입력 Input Measurement Load Measurement VAC Freq V IN I IN P IN V PF %ATHD OUT I OUT P OUT Efficiency (V RMS) (Hz) (V RMS) (ma RMS) (W) (V DC) (ma DC) (W) (%) 195 50 194.95 87.09 16.600 0.978 15.86 42.0250 339.840 14.294 86.11 210 50 209.96 81.96 16.717 0.972 17.19 42.0210 342.990 14.425 86.29 220 50 220.00 79.41 16.901 0.967 17.79 42.0320 346.830 14.590 86.33 230 50 229.95 76.75 16.995 0.963 18.27 42.0280 348.660 14.666 86.30 240 50 239.98 74.05 17.021 0.958 18.75 42.0110 348.910 14.671 86.19 265 50 264.95 68.30 17.029 0.941 20.7200 41.9870 347.950 14.621 85.86 16.3.2 액티브댐퍼사용 VAC (V RMS) 입력 Input Measurement Load Measurement Freq (Hz) V IN (V RMS) I IN (marms) P IN (W) PF %ATHD V OUT (V DC) I OUT (ma DC) P OUT (W) Efficiency (%) Effiency Improvement (%) 195 50 194.95 85.87 16.314 0.975 16.77 42.1030 342.590 14.436 88.49 2.38 210 50 209.96 81.25 16.517 0.968 17.96 42.1070 346.400 14.598 88.38 2.09 220 50 219.99 78.59 16.672 0.964 18.32 42.1070 349.130 14.713 88.25 1.92 230 50 229.94 75.91 16.749 0.960 18.79 42.0950 350.030 14.747 88.05 1.75 240 50 239.98 73.25 16.773 0.954 19.25 42.0730 349.740 14.727 87.80 1.61 265 50 264.95 67.81 16.825 0.937 21.3300 42.0480 348.750 14.676 87.23 1.37, Inc.
