DC–DC converters, as their name implies, are electrical devices that convert direct current (DC) power from one form to another. For instance, low voltage DC can be converted to higher voltage DC, low current DC can be converted to higher current DC, or even AC. As a result, these converters are commonly used in many applications. The STMGFW154815-JN3 is one such DC–DC converter which has specific uses as well as general applications where it can be used. This article outlines the application field of the STMGFW154815-JN3 and details its working principle.

Application Field of STMGFW154815-JN3

The STMGFW154815-JN3 is a high-performance, low-ripple, isolated DC–DC converter designed to provide a regulated output voltage. It is mainly used in devices that require very stable DC power input such as robotics, motor control, radios, laptops, and various type of computers. This device is also suitable for battery-powered devices because of its very low ripple current output. It is an ideal choice for various telecommunication, industrial and automotive applications.

The STMGFW154815-JN3 is suitable for negative and positive output voltage and can provide up to 15V of output potential, as well as up to 48V of input voltage. It features an adjustable remote on/off control and voltage feedback pin. Furthermore, it includes a built-in EMI filter which allows for easy connection to a mains power line, reducing interference.

Working Principle of STMGFW154815-JN3

The STMGFW154815-JN3 works on the principle of converting an input voltage into an output voltage through a series of electrical components. The input voltage is rectified and converted into a polarity-unaltered and steady form. This converted signal then passes through a filtering unit to reduce harmonic noise and narrow down the signal frequency. After this, the signal passes through an isolation transformer which reduces lead noise and limits a high noise current (up to 1500mA) generated by the large current through the primary winding to a low-level current which passes through the secondary side of the transformer. Next, the signal passes through a power transformer, where the secondary side of the transformer converts the input voltage to a regulated output voltage. Finally, the rectifier diode is used to convert the AC to DC and the regulator is used to keep the output voltage fixed.

The STMGFW154815-JN3 is a reliable DC–DC converter as it features an overload protection, over-temperature protection, and a thermal shutdown. It also has built-in soft-start and hiccup mode protection which provide reliable operation in case of accidental short circuits. Additionally, the device features a wide operating temperature range of -40°C to +85°C.

Conclusion

The STMGFW154815-JN3 is an efficient DC–DC converter with a wide application field. Its distinctive feature is the low ripple current output, making it suitable for battery-powered devices. It features an adjustable remote on/off control and voltage feedback pin and includes an EMI filter and an overload protection function. Its working principle is converting an input voltage into an output voltage through a series of electrical components. As a result, it is a great choice for various applications such as robotics, motor control, laptops, and radios.
