25-Sep-13 DER-387 5.1 W Non-Isolated Buck Using LYT0006D 중요사항 : 이기판은안전절연거리요구사항에맞도록디자인되었지만엔지니어링프로토타입은아직기관승인을받지않은상태입니다. 따라서 AC 입력을프로토타입보드에제공하도록절연트랜스포머를사용하여모든테스트를수행해야합니다. Page 3 of 40 Power Integrations
DER-387 5.1 W Non-Isolated Buck Using LYT0006D 25-Sep-13 1 소개 이문서에서는초소형벅토폴로지의 LYTSwitch TM -0 제품군 (LYT0006D) 을사용하는비용효과적인파워서플라이에대해설명합니다. 이파워서플라이는 90VAC~132VAC 의입력전압범위에서작동합니다. 벅토폴로지를사용하게되면 DC 버스전압이충분히높기때문에 38 V 출력을지원할수있습니다. 벅컨버터에서는출력전압이항상입력전압보다낮아야합니다. 또한출력전압이 LYTSwitch-0 의최대듀티사이클에의해제한되며입력전압이출력전압보다커야합니다.

PF 성능을높이도록입력단필터를댐핑하기위해저항 R1 이사용됩니다. 또한커패시터 C1 과 C2 를에너지저장용으로사용하여라인노이즈를줄이고라인서지에대해보호합니다. 4.2 LYTSwitch-0 LYTSwitch-0 은우수한라인레귤레이션과 0~100 C(LYTSwitch-0 케이스온도 ) 의온도레귤레이션을달성하는간편하고비용효과적인 LED 드라이버를구현하도록최적화되어있습니다. 파워인덕터와센싱저항의균형을이루어최상의라인레귤레이션을달성하기위해 PIXl 스프레드시트를사용합니다. 총입력커패시턴스도어느정도영향을미치지만성능을최적화하기위해서센싱저항 (R2, R3) 을조절해보정할수있습니다. LYTSwitch-0 제품군에는전구의온도가과도하게높아진경우파워서플라이를보호하기위한써멀제한기능이내장되어있습니다. 벅컨버터스테이지는파워 MOSFET 스위치를포함한 LYT0006D(U1), 프리휠링다이오드 (D1), 센싱저항 (R2, R3), 파워인덕터 (L2), 출력커패시터 (C5) 로구성됩니다. 컨버터는역방향전류의사이클을제한하기위해서대부분 DCM 으로작동합니다. 스위칭손실을최소화하기위해패스트프리휠링다이오드를선택했습니다. 4.3 출력정류 우수한효율을달성하고온도를낮추기위해패스트출력다이오드 (D1) 를사용했습니다. LED 애플리케이션의일반적인인클로저주변온도는 70 C 를초과합니다. t RR (<35ns) 이낮은출력정류기가권장되는데, 이는 t RR 이낮으면다이오드가역블로킹모드로전환되는동안파워 MOSFET 등에서스위칭손실이최소화되기때문입니다. 4.4 출력피드백 스위칭사이클을생략함으로써레귤레이션을유지합니다. 출력전류가증가하면 FB 핀의전압이높아집니다. 이값이 V FB 를초과할경우전압이 V FB 아래로줄어들때까지후속사이클이생략됩니다. 전류가 R2-R3 에서센싱되고 C4 에의해필터링된후정확한레귤레이션을위해 FB 핀으로공급됩니다. 우수한라인레귤레이션을달성하기위한 Page 9 of 40 Power Integrations
DER-387 5.1 W Non-Isolated Buck Using LYT0006D 25-Sep-13 핵심은최소인덕턴스가계산된후파워인덕터와센싱저항의값이균형을이루는것입니다. 바이패스커패시터 (C4) 를 FEEDBACK 핀과 SOURCE 핀사이에연결하여출력전류센싱중에전력손실을줄이는데도움이되도록했습니다. 이커패시터는 FB 핀으로공급되는피드백전류정보를샘플링하고홀딩하기위해작동합니다. FB 핀과 C4 사이에제한저항이필요없습니다. 왜냐하면피크전압이디바이스핀의최대정격입력전압을초과하지않기때문입니다. 4.5 오픈부하보호없음 이기기에는오픈부하보호기능이없습니다. Power Integrations, Inc. Page 10 of 40

These missing pulses are present every time the sense resistor (R2, R3) voltage-drop reaches 1.65 V. The unit will enter into auto-restart if there is not at least one missing pulse within 50 ms. For some designs wherein the power inductance is high and operating mostly in CCM, a reverse current may be present. One way to avoid this is by increasing the device size or increase input capacitance or adding a blocking diode in the drain. See AN-60 for more details. Figure 21 90 VAC, 60 Hz, 38 V LED.
