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. The preferred option for professional dimming chips in Guangzhou is the N6705C output on the oscilloscope. Efficiency testing is usually the most important test for constant current chip to constant current chip converters. 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.
Common faults or incorrect programming in the control board of output voltage rise components can lead to the application of several switch mode power supplies, such as other switch mode power supplies or charging battery magnetic induction transmission lines connected to local working voltage magnetic induction instead of remote control of magnetic induction short plug-in output terminals, which can cause overvoltage and cause surge in charging and discharging current of the components. The impact current of large component components causes excessive current due to component loads, which is related to the occurrence or specific existence of component circuit faults. The software wiring short circuit faults of the detection system for large current components are mostly protected by constant current chip power supplies, which can protect equipment from destructive voltage or current. This is called overvoltage protection and overcurrent protection.

The constant current mode only adjusts the output current below the limit current, but cannot completely turn off the output. In constant current mode, when the voltage drops below the specified voltage setting, the power supply continues to output current. Overcurrent protection (OCP) power supply circuits are dedicated to maintaining components from being damaged by excessive current. In contrast to constant current power supply methods, overcurrent protection may completely shut off the output to prevent excessive current from injecting into the components. When the overcurrent protection is activated and the switching power supply is switched to a constant current power supply mode, the maintenance power circuit will open and turn off the output.
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.
