Abstract

본 발명의 장치는 다수의 디지탈 집적 회로와 같은 원격 부하(RLOAD)에 전력을 제공한다. 상기 전력은, 예컨대 본 장치의 인쇄 회로 기판의 주변상에 장착된 제1의 다수의 접속기 P1핀을 통해 부하로 푸팅된다. 상기 부하에서의 전압(RLOAD)을 모니터하기 위해 피드백경로(FB)가 상기 부하로부터 본 장치로 제공된다. 상기 피드백 경로가 접속기의 제2다수의 핀을 통해 장치로 루팅된다. 장치의 테스팅을 용이하게 하기 위해, 장치의 출력이 저항(R2)에 의해 피드백 경로로부터 분리된다. 본 장치의 출력 전압이 부하가 안전하게 참을 수 있는 레벨을 초과하는 것을 막기 위해 저항과 병렬로 연결된다.The device of the present invention provides power to a remote load (R LOAD ) such as a number of digital integrated circuits. The power is footed into the load through a first plurality of connector P1 pins, for example mounted on the periphery of the printed circuit board of the apparatus. A feedback path (FB) is provided to the device from the load to monitor the voltage (R LOAD ) at the load. The feedback path is routed through the pins of the second plurality of connectors to the device. To facilitate testing of the device, the output of the device is separated from the feedback path by resistor R2. The output voltage of this device is connected in parallel with the resistor to prevent the load from exceeding a level that can safely be tolerated.
