DC-DC converters are devices that convert direct current (DC) from one voltage to another, and are used in a variety of applications. The VI-21Z-IV-F2 is a DC-DC converter manufactured by Intersil that is specifically designed to meet the requirements of space applications. It is a two-channel, low-noise power supply that can produce up to 2.2 volts DC at a maximum current of up to 1.5 amps.

The VI-21Z-IV-F2 has a wide range of applications. It can be used in a variety of space applications such as satellite payload systems and spacecraft power systems. It can also be used in applications such as power supplies, communication systems, automotive electronics, and many other applications that require a stable, low-noise DC power supply.

The VI-21Z-IV-F2 is a high-performance converter with superior noise rejection and accuracy. It is capable of providing extremely low noise and stable output voltages over a wide range of loading conditions. The VI-21Z-IV-F2 also incorporates a slew rate control feature, which is designed to reduce the output voltage noise, as well as an adjustable input voltage range.

The VI-21Z-IV-F2 utilizes a buck-boost topology, which allows the input voltage to be adjusted from a minimum of 10 volts (V) to a maximum of 28 volts (V). It has an adjustable output voltage range of 0V to 14V, and an adjustable current limit of up to 1.5 amps. The VI-21Z-IV-F2 also contains a soft start feature, which helps protect the output voltage from overshoot during startup.

The VI-21Z-IV-F2 operates on a hysteretic control principle. This is a non-linear control system in which the output is controlled using an input voltage signal. In this system, the output voltage is adjusted depending on the input voltage. If the input voltage is higher than the output voltage, the output voltage is increased; if the input voltage is lower than the output voltage, the output voltage is decreased. The hysteretic control principle helps the VI-21Z-IV-F2 to maintain a stable and accurate output voltage over a wide range of loads.

The VI-21Z-IV-F2 has a wide temperature operating range of -55 °C to +125 °C and can withstand high shock and vibration levels, making it an ideal choice for space applications. The input-output isolation of the VI-21Z-IV-F2 is greater than 500VDC, which helps to protect sensitive components from damage due to static electricity.

In conclusion, the VI-21Z-IV-F2 DC-DC converter is a high-performance device designed and built to meet the stringent requirements of space applications. It offers a wide range of features and benefits, including an adjustable input voltage range, adjustable current limit, hysteretic control, and wide temperature operating range. The VI-21Z-IV-F2 is an ideal choice for applications that require a low-noise power supply.
