电源模块是一种可以直接贴装在印刷电路板上的电源转换器，按变换方式一般分为AC转DC或DC转DC。随着科技的发展，电源体积趋向模块化和小型化，于是出现了电源模块。其集成度最高，将开关电源的主要电路集成在芯片中，可以实现宽频调制、隔离及多种保护等功能。

常见的基本原理由以下部分组成，输入整流滤波器，包含整流杯和输入滤波电容。单片开关电源，包括功率开关管、控制器及MOSFET。还有高频变压器、漏级钳位保护电路、光耦反馈电路、输出整流滤波器、偏置电路等部分组成。

电源模块通过输入整流滤波器─般可以适配交流B5~265V或直流100~370V的输入电压范围，频率有47~40OHz选择，常规一般为50/60Hz。因为它具有小体积、高集成度、高性价比和最佳性能指标，只需要最简的外围电路，配上少量分立式元件即可使用。并且拥有高效率、高可靠性、设计灵活等优点，现已成为开发设计中小功率开关电源的优选集成电路。

The power module is a power converter that can be mounted directly on the printed circuit board, which is generally divided into AC to DC or DC to DC according to the conversion method. With the development of science and technology, the volume of power supplies tends to be modular and miniaturized, so there is a power module. The main circuit of the switching power supply is integrated in the chip, which can realize the functions of broadband modulation, isolation and a variety of protection.

The common basic principle consists of the following parts, the input rectifier filter, including the rectifier cup and the input filter capacitor. Monolithic switching power supply, including power switching tube, controller and MOSFET. There are also high frequency transformer, leakage clamp protection circuit, optocoupler feedback circuit, output rectifier filter, bias circuit and other parts.

The power module can generally adapt the input voltage range of AC B5~265V or DC 100~370V through the input rectifier filter, and the frequency is 47~40OHz, which is generally 50/60Hz. Because it has a small size, high integration, high cost performance and the best performance indicators, only the simplest peripheral circuit is required, with a small number of discrete components can be used. And has the advantages of high efficiency, high reliability, flexible design, etc., has become the optimal integrated circuit for the development and design of small and medium power switching power supply.
