1. Application field of Q8025PH5-W

As a type of pulse power supply module, Q8025PH5-W has a wide range of applications. It can be used in communications, industrial control and various systems with battery and power supply, especially in 3G/4G drill machine systems, set-top boxes, automotive devices, and outdoor broadband remote equipment, etc.

Q8025PH5-W module has excellent power supply performance due to its high conversion efficiency, low circuit voltage, low power dissipation and stand-by current. In addition, its system has features of low system cost, high reliability and strong anti-interference ability, which makes it an ideal power supply module for many fields.

2. Working principle of Q8025PH5-W

The working principle of the Q8025PH5-W module is based on the switching power supply technique. The module consists of four parts, namely an input voltage source, a power switch, an output voltage and a feedback control loop. Firstly, the pulse power supply module will convert the output voltage into a fixed frequency and pulse-width on the main pulse switch, then the output voltage can be obtained and regulated by changing the duty cycle of the main pulse switch.

When the output voltage is lower than the set value, the module will increase the duty ratio, so that the output voltage can increase and reach the set value. When the output voltage is higher than the set value, the module will reduce the duty ratio, so that the output voltage can decrease and reach the set value, thus achieving the purpose of output voltage regulation.

3.Conclusion

Q8025PH5-W is a type of pulse power supply module with advanced features and excellent performance. It has a wide range of applications, which can be used in communications, industrial control and various systems with battery and power supply. The working principle of Q8025PH5-W is based on the switching power supply technique, which can effectively regulate the output voltage to ensure high reliability and strong anti-interference ability.
