DC-DC converters are devices that convert power from one source to another, allowing the output voltage to be controlled and regulated. They are frequently used to step up or down low voltages, and are available in a variety of different forms, including linear, switched-mode, resonant, and transformer-based designs. The VI-21Z-MX-F1 is a switched-mode DC-DC converter from Vicor Corporation which features a wide secondary output voltage range, allowing the user to configure the output from 2.5 to 15 volts. The internal components are protected against both under- and over-voltage conditions, and the device has a high switching frequency that provides excellent transient response and low electromagnetic interference (EMI).

The VI-21Z-MX-F1 is specifically designed for high-power applications such as Variable Speed Drive (VSD) motors and robotics, industrial automation and motor control, and power conditioning in renewable energy systems such as wind turbines. It enables system designers to build control solutions that are efficient, compact, low cost, and highly reliable, with a long operating life and a very low Total Cost of Ownership (TCO).

The device features a two-stage topology, with a primary stage that is based on a proprietary Vicor DC-DC converter design, and a secondary stage that uses a standard Flyback converter circuit. The primary stage features a wide input voltage range, low output ripple, and efficient transient response, allowing the device to provide reliable performance in a variety of different operating conditions. The secondary stage provides further protection against component failures, and provides additional cost savings by helping to reduce the number of external components.

The device is also equipped with a range of sophisticated control features, including intelligent active current sharing, adjustable output voltage control, programmable startup and shutdown timing, and an over-temperature protection (OTP) circuit that monitors the output voltage and current. It has a very low standby power consumption, and supports both synchronous and asynchronous modes of operation. The device also features a wide input voltage range, high efficiency, and a wide operating temperature range of -40°C to +105°C.

In summary, the VI-21Z-MX-F1 is a high reliability, high-performance DC-DC converter that is designed for use in a variety of applications, including robotics, industrial automation, motor control, and renewable energy systems. It features a two-stage topology with a primary stage based on Vicor’s proprietary converter design, and a secondary stage with a Flyback converter circuit. The device provides a wide range of sophisticated control features, such as active current sharing, adjustable output voltage control, and an OTP circuit that monitors the output voltage and current. It also has a wide input voltage range, high efficiency, and a wide operating temperature range, making it a reliable choice for high-power applications.
