The AC DC Desktop, Wall Adapters are electrical appliances that all contain a charging module, such as the SDI65-12-UC-P5. This module converts AC electricity from the wall socket into DC electricity. This article will explain the application field and the working principle of the SDI65-12-UC-P5 module.

The SDI65-12-UC-P5 module is designed for applications in mobile phones and other portable electronics including digital cameras and video game consoles, as well as certain electric tools and appliances. This module offers two power levels that switch when the input voltage changes and both have a wide range of compatibility. The high power level provides increased amperage for powering larger devices, while the low power level is designed to save energy while providing efficient, effortless battery recharging.

The module is also designed with a temperature and overcurrent protection switch, allowing users to adjust the charging rate to avoid overloading or overheating different parts. Further, it offers a low standby power consumption of less than 0.5 Watts.

The working principle of the SDI65-12-UC-P5 module is based on the same active power factor correction and switch-mode power conversion technology found in energy efficient AC adapters and power converters. This technology employs two main components, the primary side power factor correction circuit and the two stage regulation circuit. The power factor correction circuit utilizes a MOSFET driver and pulse-width modulation (PWM) controller to regulate the current and voltage in order to maintain a preset input power factor. The switching power circuit is composed of two switching transistors, one single-pole/double throw (SPDT) power status flip-flop, a converter IC, two power switches, two Zener diodes, two resistors and two capacitors. These components control the input voltage, adjusting its level accordingly, promoting energy savings and low standby power consumption. Finally, the two stage regulation circuit ensures that power delivered to the device matches the required level.

Overall, the SDI65-12-UC-P5 module is an efficient and powerful AC DC Desktop, Wall Adapter that provides energy-efficient recharging capabilities. It is suitable for powering mobile phones and other electronic devices and can also be applied to certain electric tools and appliances. Moreover, it offers two power levels and has a low standby power consumption. The working principle of this module involves active power factor correction and a two stage regulation circuit, utilizing MOSFET drivers, pulse-width modulation controllers, switching transistors, power status flip-flops, and other components for efficient power conversion.
