The T1023-07C switching power module is a modular package of discrete components on the switching power supply to form a smaller volume and higher power density module power supply. Its internal circuit is also a switching power supply. Switching power modules can be divided into AC/DC and DC/DC types. Among them, the DC/DC converter has been modular, and the design technology and production process have been mature and standardized at home and abroad, and has been recognized by users. However, due to its own characteristics, AC/DC modularization has encountered more complex technical and process manufacturing problems in the modularization process.

T1023-07C switching power module has the advantages of simple design, flexible change, low technical requirements, and can be used in input protection circuit, remote control switching circuit, etc. For example, the remote switch operation of the module power supply is carried out through the REM end, and there are generally two control methods. One is that REM is connected to -VIN (reference ground) to achieve remote shutdown, or REM is suspended or connected to +VIN to make the module work. The other is that REM is connected to VIN to achieve remote shutdown, or REM is connected to +VIN to make the module work, or REM suspension to achieve “suspension shutdown”.

In addition, the DC/DC conversion in the T1023-07C B switching power supply module involves DC chopper technology, that is, converting a fixed DC voltage into a variable DC voltage. There are two main working modes of chopper: pulse width modulation and frequency modulation. The pulse width modulation method keeps Ts (period) unchanged and changes ton (on-time), while the frequency modulation method keeps ton unchanged and changes Ts, but this method is easy to cause interference.

For the application of switching power modules, sometimes it is necessary to perform parallel expansion to meet the larger current output requirements. In parallel expansion, it is necessary to carefully design the lead resistance to achieve the current sharing effect, but the number of parallel modules should not be too large to avoid system stability problems.
