摘要： A jig for testing the printed circuit boards utilizes the adjustable guide members to easily position different sizes of circuit boards on a working plate, wherein the working plate can smoothly slide up and down along the guide columns and the elastic members without jamming. The second surface of the working plate is formed with a concavity and several bulged sections to stably place the circuit board without deformation, and therefore the soldering points of the circuit board can uniformly touch the tips of the probes which are retractably installed in the through holes of the base. By using the assembling base, the maintenance of the internal structure of the base can be improved.

摘要： A PWM controller for controlling a switching voltage regulator comprises a first comparator, a second comparator and a third comparator. The first comparator is configured to detect voltages of a first node and a second node so as to determine whether to stop the PWM controller. The PWM controller is stopped if a first potential is lower than a threshold, and the first potential derives from the voltage of the first node by a level shift of a first voltage difference. The second comparator is configured to detect the voltage of the first node and then to compare the voltage with a power reference voltage so as to determine whether the PWM controller receives necessary power. The third comparator is configured to compare the voltage of the second node with an enable reference voltage so as to determine whether to disable the PWN controller.
