It is important to ensure that the device can handle the internal ripple of the converter and the ripple caused by unstable power supply. a: N6705A is set to generate 500mVpp ripple on a 9V output. 3b: N6705C output on the oscilloscope. Guangzhou professional dimming chip sales efficiency testing. Generally speaking, the most important test for constant current chip to constant current chip converters is efficiency testing. This is particularly true for battery powered devices, as efficiency directly affects the battery's lifespan. The efficiency of a converter is the ratio of output power to input power. To test efficiency, a constant current chip power supply should be used to provide power to the converter and an electronic load should be used to obtain power from the converter. The efficiency of constant current chip to constant current chip converter design is usually affected by the input voltage and the power consumption of the load.
The delay setting of N6705C is very simple and beneficial for precise output voltage opening sorting. The main causes of device failures are overvoltage and overcurrent conditions. Sometimes the duration of overvoltage and overcurrent conditions is very short, and sometimes it lasts until it is detected. Under any circumstances, overvoltage and overcurrent can be very dangerous. By controlling the current and voltage output of the power supply, it is possible to prevent the tested equipment from exceeding the fault limit or approaching the fault. There are many reasons for overvoltage or overcurrent, including internal circuit faults.

Linear power supplies have low common mode noise current and typically operate at low frequencies. However, if the technical specifications of switch mode power supplies include low common mode currents, you can successfully use them. Based on experience, super 2-3-0m may cause common mode current failure. Based on the experience of a total mode current of 20-30a, a fault may occur. The connection between the tested device and the power supply reduces conducted noise by reducing the grounding circuit. In an ideal state, there should be only one grounding connection. However, in a framework system, it is inevitable that multiple grounding positions will occur, and it is necessary to isolate the constant current chip distribution circuit and other transmission paths that bear the grounding current.
Prevent imbalanced inductors in load transmission lines; It is best to immediately connect to the tested component, such as a shielded twisted pair. A shielded twisted pair (STP). In order to better ensure that the design scheme is reasonable and efficient, you must ensure that the power supply system and power consumption control module are all working properly. In this chapter, we discussed four important aspects that are beneficial for maintaining and qualitatively analyzing power consuming components.
