DC-DC converters are widely used in many industries, such as transportation, communications, industrial automation, computer peripheral and renewable energy. One of the most popular type is electronic switch-mode power supply, which converts direct current (DC) power from one voltage level to another. In this article, will be focusing on JCK4024S05, an isolated switch-mode DC-DC converter with ultra-wide input voltage ranges of 4.5 to 40V and output voltage ranges of 1.2 to 24V. JCK4024S05 applications include: generators, industrial control systems, medical instruments, communication systems, distributed power systems, unmanned aerial vehicles, and the automotive field. The wide input voltage ranges can easily adapt to different batteries, secondary power supplies, and different rectified AC grid voltages. JCK4024S05 is designed with a powerful and efficient synchronous rectification power topology to increase device reliability and reduce power consumption. It offers full protection functions such as short-circuit protection, overload protection, overvoltage protection and others. The unique drain-source reverse current protection design safeguards the system while protecting internal components from damage. JCK4024S05 working principle can be explained by its block diagram. It can be divided into the following four blocks: power input, power factor correction, rectification and regulation, and output. First, the alternating current (AC) passes through the power input block and is rectified by the rectification bridge. After the rectification, the DC voltage is then converted into a stabilized sine wave by the power factor correction (PFC) converter. The stabilized sine wave is then rectified by the full bridge rectifier, resulting in a constant DC voltage. This DC voltage is then passed through the output regulation block to obtain the desired output voltage. The output regulation block uses the pulse-width modulation (PWM) technique to adjust the voltage. It also has an output overvoltage protection circuit for reliable operation of the converter. Finally, the output voltage is filtered and regulated to a stable voltage level. The constant output current ensures that the device operates at its optimal power.In summary, JCK4024S05 is an isolated switch-mode DC-DC converter with ultra-wide input voltage ranges and output voltage ranges. It is widely used in various fields, including transportation, communications, industrial automation and renewable energy. Its unique protective functions make it highly reliable and safe to use. Its working principle is based on a four-block circuit system, which includes power input, power factor correction, rectification and regulation, and output.
