DC DC Converters

A DC-DC converter is a device that takes a source of direct current (DC) power and converts it into a different direct current voltage for a variety of uses. The range of applications includes voltage regulation, power conditioning, and isolating sensitive circuitry from power supply noise and other sources of interference. DC-DC converters come in a variety of shapes and sizes and are often designed for specific operating conditions such as input voltage, output voltage, temperature range, power output, and circuit topology.The most common type of DC-DC converter is the step down converter, also known as a buck converter. A buck converter works by changing the amount of power that is delivered to the load, thereby reducing the input voltage to match the desired output voltage. This is done by feeding the input voltage into a switching circuit, which is then used to control the amount of energy that is sent to the load. The amount of energy is controlled by the switch’s duty-cycle, or the amount of time the switch is turned on. A buck converter is particularly useful when the desired voltage is lower than the input voltage, as it can reduce the input voltage without the need for additional components.The VI-B1Z-CU-B1 DC-DC converter is a high-efficiency, step-down DC-DC converter that is specifically designed for operating in harsh intermittent DC-powered applications. It can regulate an input voltage of up to 55V (DC) down to a selectable output voltage of 30V/24V/18V (DC). It also features built-in protections against over-voltage, over-current, and over-temperature conditions.The VI-B1Z-CU-B1 is a buck-converter type of DC-DC converter, meaning it regulates its output voltage by reducing the amount of input power that is sent to the load. The VI-B1Z-CU-B1’s switching circuit works by switching on a transistor circuit at a high frequency and for a given amount of time, decreasing the amount of power sent to the load and increasing the amount of time the transistor is off, thus lowering the output voltage.The VI-B1Z-CU-B1 also features a built-in shutdown function which shuts off the converter when the load current reaches a pre-determined current limit. This safety feature ensures that the converter will not damage the system in the case of an overload or short-circuit.Finally, the VI-B1Z-CU-B1 features variable frequency/duty-cycle control to allow for power savings under light load conditions. This control adjusts the frequency and duty-cycle of the switch, decreasing the amount of power that is sent to the load and, therefore, decreasing the amount of power consumed and wasted.In summary, the VI-B1Z-CU-B1 is a high-efficiency, step-down DC-DC converter that is designed for harsh intermittent DC-powered applications. It can regulate an input voltage of up to 55V (DC) down to a selectable output voltage of 30V/24V/18V (DC). It also features built-in protections against over-voltage, over-current, and over-temperature conditions, as well as a built-in shutdown function. Finally, it features variable frequency/duty-cycle control to allow for power savings under light load conditions.
