DC-DC converters are an important, and often overlooked, component of modern electronic design. The TEC 2-2421 is one such example of a DC-DC converter and has a wide range of applications, from aerospace and automotive electronics, to medical equipment and communications infrastructure. The purpose of this article is to explain the working principle and application areas of the TEC 2-2421.

The TEC 2-2421 is a single-output, low-voltage DC-DC converter designed with advanced feedforward and hysteretic control techniques. At the core of the device are two DC-DC buck converters working together in a master/slave topology. The master converter is a non-inverting converter with an external control loop and can provide precise current regulation for high-frequency fault suppression. The slave converter is a non-inverting buck converter and provides the output ripple cancellation.

With its advanced control techniques, the TEC 2-2421 is ideal for a wide variety of applications, including powering microprocessors and digital signal processors (DSPs). The device can also be used for the power supply of portable electronics, such as mobile phones and laptops. Its high power density and wide input voltage range (9 – 36V) make it an ideal solution for automotive, aerospace and industrial applications.

The TEC 2-2421 also features a wide range of output voltages which programme via graphical user interface or an external resistor divider. This feature offers great flexibility to the user, allowing the output voltage level to be changed easily and without the need for manual adjustments. The device also has several built-in safety features, such as short-circuit and over-temperature protection.

The TEC 2-2421 employs a constant-frequency, hysteretic and/or feed-forward regulation technique that allows precise current control. This makes the device ideal for low-voltage microprocessor applications, where precise current regulation is required. Additionally, the device has a low output ripple and no-load power consumption, making it ideal for decentralised power supply systems.

To sum up, the TEC 2-2421 is a low-voltage DC-DC converter, designed for a wide range of applications. With its advanced feedforward and hysteretic control techniques, the device is capable of providing precise current regulation for the power supply of microprocessors, DSPs, and other low-voltage digital electronics. Its wide input voltage range and output voltage programming feature, combined with low no-load power consumption and output ripple, make it an ideal choice for aerospace, automotive and many other industrial applications.
