DC-DC ConvertersA DC-DC converter is an electronic device used to convert direct current (DC) from one voltage level to another. As the name implies, a DC-DC converter works by converting DC power from one voltage to another using an intermediate power conversion process. The process typically involves changing the input voltage or current of the DC power to an adjustable form (such as a pulse width modulation (PWM) signal), which is then converted into another form of DC power at a different voltage. DC-DC converters are used in various industries such as automotive, telecommunications, computing, and military applications.The V28C28H100BL is a popular model of DC-DC converter. This particular model is a wide input range buck converter, capable of providing primary voltage output ranges of 8-28V DC from a 2.8-28V DC input voltage source. It is configurable to source or sink current, and provides protection from over-voltage, over-current, short circuit, and overtemperature conditions, as well as reverse battery protection. It also contains an adjustable soft start up feature.The V28C28H100BL is typically used in applications that require robust voltage regulation and reliable operation with reduced heat dissipation, when compared to other types of DC-DC converters. This device is built to withstand harsh environments and is well-suited for applications such as automotive, telecommunications, industrial, and consumer electronics products.In terms of its working principle, the V28C28H100BL uses a MOSFET based, buck topology, voltage regulator circuit. It works by using a MOSFET switch in series with the input voltage source, and a second MOSFET switch in parallel with the output load. The two MOSFETs are controlled by an internal control circuit based on a pulse width modulation (PWM) technique. This allows a variable duty cycle to be used to step down the input voltage to the required output voltage.The V28C28H100BL is capable of very high output currents. This is achieved by using an internal bootstrap circuit that provides the necessary voltage level to the MOSFETs, allowing them to operate at high current levels. The device greatly reduces overall power dissipation, because of its unique circuit configuration which requires slightly higher input voltages. This allows the regulator to operate efficiently even at low output power levels.In summary, the V28C28H100BL is a high power MOSFET based buck converter. It works by using a voltage regulator circuit based on a PWM technique, which allows it to step down the input voltage to a required output voltage. The device is designed to withstand harsh environments, is capable of sourcing and sinking current, and is well-suited for various applications.
