DC DC Converters

DC-DC converters are power electronic devices used to convert a source or sink of power from one DC voltage to another, using both electrical and electronic components. The SUS100515B is an example of a DC-DC converter designed to step down or step up voltages. This article will discuss the application field and working principle of the SUS100515B.The SUS100515B is a high power GaN-on-SiC monolithic DC-DC converter. It is designed to operate as a buck converter, meaning it is able to step down the voltage from a higher level to a lower level. Its main features include high power density, low overtemperature triggering current, and low output ripple.The SUS100515B is most commonly used in battery operated applications and other power sources with a wide input voltage range. It is also used in battery charging applications, such as solar cell arrays and automotive batteries, for it provides high efficiency over the entire input range. In addition, the SUS100515B can be used in data centers, servers, and networking applications.The SUS100515B works on the Buck converter principle, which involves a DC-DC switch mode power supply. This switch mode power supply can convert low voltage to high voltage or vice versa. In this device, buck converter operating linear regulator principle is used to achieve efficiency. The device consists of a voltage reference circuit, error amplifier, driver, and a switching device.The voltage reference circuit is the first component of the SUS100515B which sets the voltage that is to be reached by the output of the device. The error amplifier compares the output voltage of the device to the reference voltage and generates an error signal. The error signal then goes to the driver which is responsible for supplying the current to the switching device that controls the operation of the switching device. The switching device is responsible for actually switching the input voltage to the output voltage.In order to control the output voltage of the SUS100515B, a feedback loop is used. The feedback loop is a combination of the error amplifier and the driver. This loop serves to regulate the output voltage. Whenever there is mismatching of the output voltage and the reference voltage, the error amplifier creates an error signal that is fed to the driver which then supplies the current to the switching device, thus controlling the output voltage.Overall, the SUS100515B is a high power GaN-on-SiC monolithic DC-DC converter which is most often used in applications such as battery operated devices and battery charging. It operates on the Buck converter principle, which utilizes a DC-DC switch mode power supply. The SUS100515B utilizes a feedback loop to regulate the output voltage and maintain accuracy.
