DC DC Switching Regulators

A DC-DC converter is an electronic component that converts direct current (DC) voltage from one level to another and regulates the output, typically transforming a low voltage by boosting it to a higher voltage. The S-8354A27MC-JQMT2U uses a DC DC Switching Regulators design to achieve this and is widely used in a variety of applications.

Application Field

The S-8354A27MC-JQMT2U is primarily used in industrial, automotive and consumer electronic and home appliances such as LCD TVs, DVD players, PC motherboards, cell phones etc. In addition to these fields, the device is widely used for the purpose of power polishing, power conditioning, voltage and frequency regulation, motor control and power conversion.

The component is particularly adept at providing highly accurate and stable voltages from a wide range of input sources. This is due to its ability to regulate input currents and adjust output voltages for a wide range of power ranges.

As a result, the S-8354A27MC-JQMT2U is suitable for applications dealing with digital ICs, producing a stable and reliable output that is not affected by temperature variations or other environmental factors. The device is also highly efficient with regard to energy saving, meaning that it can help extend the battery life of the device it’s applied to.

Working Principle

The S-8354A27MC-JQMT2U is an adjustable, multi-output voltage DC-DC converter that employs pulse width modulation (PWM) technique. This method involves the switching of a short burst of current with a ‘square wave’, meaning that the output voltage can be accurately regulated, providing the required voltage within a very short time.

The device uses a Pulse Frequency Modulation (PFM) controller, which starts its operation with the input voltage applied to its input terminals VIN. The PFM controller then produces a Pulse Width Modulation (PWM) signal, varying the output voltage, allowing it to accurately measure the input and make the required adjustments.

When the switch is closed, the Pulse Frequency Modulation (PFM) controller will monitor the Rise Time (T) of the input voltage. Depending on the slope of the input voltage, the PFM controller will adjust the open and close times of its Pulse Width Modulation (PWM) signal, regulating the rise time of the output voltage.

The S-8354A27MC-JQMT2U is often used in power supply applications, such as PC motherboards, because it can provide a precise control of the output voltage, allowing for additional features such as soft start, power sequencing and remote sensing.

Conclusion

The S-8354A27MC-JQMT2U is a DC DC Switching Regulator designed for a variety of applications, mainly in industrial and consumer electronics. It is able to regulate input currents and adjust output voltages according to the type of power supply used, allowing for greater accuracy and stability. It is able to provide a highly precise control of the output voltage, and is often used in power supply applications famous for their energy saving and remote sensing capabilities.
