DC-DC switching regulators are often used as multiple output power supplies, providing voltage regulation as well as galvanic isolation between the input and the output. The S-8351A55MC-J3OT2G, manufactured by CUI Inc., is a DC-DC switching regulator that is designed for use in a wide variety of applications. This article will cover the applications of the S-8351A55MC-J3OT2G, as well as the general principles behind its working.

Applications of the S-8351A55MC-J3OT2G

The S-8351A55MC-J3OT2G is a high efficiency, non-isolated DC-DC switching regulator. It is primarily designed to provide a regulated output voltage within a wide input voltage range, making it suitable for use in many different applications. The S-8351A55MC-J3OT2G is ideal for use in telecommunications equipment, industrial process control systems, medical equipment, consumer electronics, aerospace and defense systems, and automotive applications.

It is particularly well-suited for use in industrial power supplies and other equipment that is subject to voltage transients or wide voltage variations as it is designed to provide a stable output voltage level over a wide input voltage range. This eliminates the need for additional components, such as filters or transient suppression devices, thus reducing the size and cost of the power supply system.

Features of the S-8351A55MC-J3OT2G

The S-8351A55MC-J3OT2G has several features that make it suitable for a variety of applications. It is designed with an adjustable output voltage and has a wide input voltage range of 8.0 to 28 VDC. The output voltage is adjustable from 1.3 V to 15 V, allowing the user to adjust it according to the specific application requirements. It also has a wide temperature range of -40°C to +85°C, allowing it to operate in a range of environmental conditions. In addition, it has a high efficiency of up to 90%.

The S-8351A55MC-J3OT2G also has an integrated MOSFET and requires no external components, which reduces its size and cost. It is also designed with a fail-safe overload protection feature that provides current and temperature protection for the output voltage. The device is also RoHS compliant and is certified to meet the EN61000-3-2 harmonic current emission standards.

Working Principle of the S-8351A55MC-J3OT2G

The S-8351A55MC-J3OT2G is a DC-DC switch-mode converter, which works on a simple and efficient “buck-boost” switching principle. This type of power supply works by converting a DC input voltage through two parallel switches, a lower voltage switch (the buck) and a higher voltage switch (the boost). As the input voltage changes, the switches turn on and off in combination and transfer energy from the input supply directly to the output, thus providing a steady output voltage.

The S-8351A55MC-J3OT2G uses a Pulse Width Modulation (PWM) control scheme. PWM is a technique for controlling power by modulating the width of the pulses of electrical current or voltage supplied to an electrical load. The S-8351A55MC-J3OT2G is designed to regulate the PWM signal and use it to control the current between the input and output. As the input voltage changes, the PWM signals are modulated accordingly, thus allowing the current to remain constant, regardless of the input voltage.

The S-8351A55MC-J3OT2G also uses an internal feedback loop to maintain a stable output voltage, while also providing protection against over-voltage and short-circuit conditions. In addition, the device includes an integrated under-voltage lockout (UVLO) feature, which prevents the converter from turning on when the input voltage is too low, thus protecting the device from damage.

Conclusion

The CUI Inc. S-8351A55MC-J3OT2G is a versatile and efficient DC-DC switching regulator. It is designed for use in a wide variety of applications and is suitable for use in industrial power supplies, telecommunications equipment, and other systems that require a stable regulated output voltage over a wide input voltage range. The device is efficient and compact, and requires no external components. In addition, it is RoHS compliant and is certified to meet the EN61000-3-2 harmonic current emission standards. Finally, the device works on a simple “buck-boost” switching principle and utilizes PWM control and an internal feedback loop to maintain a stable output voltage.
