For the TRIM output pin, the center of the output potentiometer and the center TRIM are all connected to +S, -S in the pin module, and the other two ends are connected to +S, -S respectively. There is no +S, and the -S ends receive the positive and negative outputs of the corresponding main circuit respectively (+S is connected to +Vin, -S is connected to -Vin), and then adjust the potentiometer. The resistance of the potentiometer is generally 5~10kΩ.
non-standard customization The ADJ output pins are divided into input adjustment and output adjustment. Output trim and output trim. The adjustment method of the TRIM pin is the same. When one end of the potentiometer is connected to the center, the output voltage can only increase the output voltage, and the other end is connected to the ground of the input.
Input protection circuit General manufacturer supply products use built-in filters, which can meet the requirements of general 24V input power supply applications. If a more demanding power system is required, non-standard customization the input filter network should be added. Either LC or π can be used but care should be taken to choose a smaller inductance and larger capacitance.
