DC-DC converters are widely used in many areas, with the ability to convert the output of one electrical source to a level suitable for a second source, and have a wide range of applications in home appliances, medical devices, telecommunications, automotive, industries, military, and aerospace. Among them, PXF4024S05 is widely used in the DC-DC converter field.

The PXF4024S05 is an isolated DC-DC converter that is specially designed and developed to suit wide variety of applications. It is a high-efficiency, low-cost device with a wide operating input voltage range of 4~36V and a wide output voltage range of 0.8~9V. The PXF4024S05 has a working temperature range of between -40℃ and + 85℃, a wide temperature range. The output is independent of the input and can be regulated by pulse width modulation (PWM) under constant current or constant voltage. It is also equipped with adjustable current limit, over voltage limit, and thermal shutdown for protection.

The key component of the PXF4024S05 is the flyback topology switching power supply, which is also called a pulse transformer. This power supply uses a transformer to step up the DC voltage of the primary side to a higher voltage level in the secondary side and provide isolation between the primary side and secondary side. It uses an inductor and a capacitor to store energy for the switching circuit to regulate the output voltage. It also uses a fast switching element to convert the primary side DC power into an AC power, which is then passed through the transformer to the secondary side to get the output.

The main features of the PXF4024S05 include two dual-level current limited and adjustable soft start, as well as 0.8~3.3 V adjustable output voltage. With high peak load efficiency (94% efficiency at 600mA output current) and low no-load output power (20mW at 5V output voltage), the PXF4024S05 satisfies the requirements for green power Ethernet applications and various energy-saving intelligent products. The device also includes a built-in over-voltage protection circuit, so it can work reliably against high-voltage input conditions. In addition, it provides a wide range of protections such as short circuit and over-temperature protection, for a safe and reliable operation.

Therefore, the PXF4024S05 can be used in various DC-DC applications, such as power Ethernet, multimedia, instrumentation, computing and other industrial or home equipment requiring a simple and reliable solution.
