14-Sep-12 RDR-313 30 W Single Output Flyback Supply 4 회로설명 4.1 입력정류및필터링 브리지정류기 BR1 이 C2 로필터링되는 AC 입력을정류합니다. 인덕터 L4, C14 및 C2 가디퍼렌셜모드및커먼모드전도성 EMI 를감쇠시키는데사용됩니다. 커먼모드 EMI 변위전류를감소시키기위해트랜스포머 T1 구성에차폐기술이사용되었습니다. 이필터배열, 차폐기술은 IC 의주파수지터링기능과함께 Y- 커패시터및 1 차측 RZCD 클램프회로가포함된이솔루션에뛰어난 EMI 성능을제공합니다. 4.2 LinkSwitch-HP 1 차측 LNK6766E 디바이스 (U3) 는오실레이터, 에러증폭기와멀티모드컨트롤회로, 스타트업및보호회로, 고전압파워 MOSFET 을모두하나의모놀리식 IC 에통합하였습니다. 전력트랜스포머의한쪽은고전압버스에연결되어있고다른쪽은 U3 의 DRAIN(D) 핀에연결되어있습니다. 스위칭사이클시작시컨트롤러가파워 MOSFET 을켜고 1 차측권선에서전류가증가하여트랜스포머의코어에에너지를저장합니다. 해당전류가내부에러증폭기의출력에의해설정된제한기준값에도달하면 (COMPENSATION(CP) 핀전압 ), 컨트롤러가파워 MOSFET 을끕니다. 출력다이오드의방향및트랜스포머권선의위상으로인해저장된에너지가 2 차측권선의전압을유도하여, 출력다이오드를순방향으로바이어스하고저장된에너지가출력커패시터에공급됩니다. BYPASS(BP) 핀에연결된커패시터 C5(0.47 F) 가 OVP( 과전압보호 ) 및 OTP( 과열보호 ) 기능을래칭으로, 레귤레이션상실보호기능을지정된 OFF 기간 ( 일반적으로 1500ms) 후자동재시작시도 ( 오토리스타트 ) 로설정합니다. 4.3 1 차측 RZCD 클램프 다이오드 D1, VR1, C3, R2 및 R3 은 LinkSwitch-HP 의전압스트레스를제한하는데사용되는 RZCD 스너버를구성합니다. 따라서피크드레인전압은일반적으로 265VAC 에서 540V 미만으로제한되어 650V 드레인전압 (BV DSS ) 에상당한마진을제공합니다. 제너 VR1 은스위칭사이클마다커패시터 C3 이완전히방전되는것을방지하여대기작업동안전력소비를줄여줍니다. 다이오드 D1, R2, VR1, C3, R5 및 R6 은 LinkSwitch-HP 의전압스트레스를제한하는데사용되는 RCD 스너버를구성합니다. 따라서피크드레인전압은일반적으로 265VAC 에서 580V 미만으로제한되어 700V 드레인전압 (BV DSS ) 에상당한마진을제공합니다.

RDR-313 30 W Single Output Flyback Supply 14-Sep-12 4.4 출력정류 다이오드 D8 에서 12V 출력의출력정류를제공하고커패시터 C12, C21 및인덕터 L5 와 C22 에서필터링을제공합니다. R13 및 C13 으로구성된스너버는 EMI 개선을위한높은주파수필터링을제공합니다. 4.5 외부전류제한설정 - 최대사이클단위전류제한은 PROGRAM(PD) 핀에연결된저항 R8 에의해설정됩니다. 이디자인에서는 23.2k 저항이최대전류제한을 LNK6766E 의기본전류제한의 60% 로설정합니다. 4.6 피드백및보정네트워크 플라이백기간동안출력전압은바이어스권선및저항분배기 (R19 및 R20) 를통해센싱됩니다. 센싱된출력전압은 FEEDBACK(FB) 핀기준값과비교해출력을레귤레이션하거나과전압상태가감지될경우스위칭을중지합니다 (OVP). 이 1 차측레귤레이션 (PSR) 솔루션은 LinkSwitch-HP 로디자인된파워서플라이로써옵토커플러 ( 파워서플라이의수명을크게감소시킴 ) 가필요하지않으므로시스템의수명을늘려줄뿐아니라시스템비용도줄여줍니다. 파워 MOSFET 온타임동안버스전압을간접적으로모니터링하기위해전압드라이버 R19 및 R20 도사용되었습니다. 스타트업시버스전압이일반적으로 100V( 브라운인기준값 ) 에도달한경우에만 IC 에서스위칭할수있습니다. 예를들어, 브라운아웃상태에서버스전압이일반적으로 40V 아래로떨어지면디바이스에서스위칭을중지합니다 ( 브라운아웃보호 ). 버스전압이과도한수준에도달하면 ( 예 : 라인서지로인해 ) 디바이스에서스위칭을중지합니다. 또한, 사이클단위전류제한은입력에따라보정되어사용가능한과부하전력을제한합니다. 자세한내용은디바이스데이터시트를참조하십시오. FB 핀에서센싱된전압은 CP 핀에서컨트롤전압을생성합니다. 저항 R7 및커패시터 C7 과 C8 은컨트롤루프보정을위해사용됩니다. 1 차측동작피크전류와동작스위칭주파수는 CP 핀전압에의해결정됩니다. Page 8 of 42

RDR-313 30 W Single Output Flyback Supply 14-Sep-12 11.6 출력리플및노이즈측정 11.6.1 리플측정기술 For DC output ripple measurements, a modified oscilloscope test probe must be utilized in order to reduce spurious signals due to pick-up. Details of the probe modification are provided in the figures below. The 5125BA probe adapter is affixed with two capacitors tied in parallel across the probe tip. The capacitors include one (1) 0.1 F / 50 V ceramic type and one (1) 4.7 F / 50 V aluminum electrolytic. The aluminum electrolytic type capacitor is polarized, so proper polarity across DC outputs must be maintained (see below).
