T1023-07C 开关电源模块是将开关电源上的分立元器件进行模块化封装，从而形成体积更小、功率密度更高的模块电源。其内部电路也是开关电源。开关电源模块可分为AC/DC和DC/DC两大类。其中，DC/DC变换器现已实现模块化，且设计技术及生产工艺在国内外均已成熟和标准化，并已得到用户的认可。然而，AC/DC的模块化因其自身的特性在模块化进程中遇到了较为复杂的技术和工艺制造问题。

T1023-07C 开关电源模块具有设计简单、变更灵活、技术要求低等优点，并可用于输入保护电路、遥控开关电路等。例如，模块电源的遥控开关操作是通过REM端进行的，一般有两种控制方式。一种是REM与－VIN（参考地）相连实现遥控关断，或者REM悬空或与+VIN相连使模块工作。另一种是REM与VIN相连实现遥控关断，或者REM与+VIN相连使模块工作，或者REM悬空实现“悬空关断”。

此外，T1023-07C B开关电源模块中的DC/DC变换涉及直流斩波技术，即将固定的直流电压变换成可变的直流电压。斩波器的工作方式主要有脉宽调制和频率调制两种。脉宽调制方式保持Ts（周期）不变，改变ton（导通时间），而频率调制方式则保持ton不变，改变Ts，但这种方式易产生干扰。

对于开关电源模块的应用，有时还需要进行并联扩容以满足更大的电流输出需求。在并联扩容时，需要仔细设计引线电阻以达到均流效果，但并联的模块数量不宜过多，以避免系统稳定性问题。

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.
