DC/DC converters are versatile and highly efficient power conversion devices which convert a DC input into a DC output. They are commonly used to convert high voltage, low current DC input to a lower voltage, higher current DC output. The most common types of DC/DC converters are switched-mode power supplies (SMPS), linear voltage regulators, and charge pumps. One of the most popular examples is the VE-23T-IW, a high power density, low cost DC/DC converter.

The VE-23T-IW is designed to convert a DC input voltage of 36V to an adjustable output voltage of 0V to 32V, with an output current of up to 100A. It is rated for a continuous output of up to 96 watts and can operate at frequencies up to 20MHz. The VE-23T-IW is an ultra-wide input voltage range buck-boost converter, which means it can handle higher input voltages than typical buck converters. This makes it ideal for applications with input voltages that can vary broadly.

The VE-23T-IW utilizes a combined voltage/current-mode control topology, providing active current limiting and improved transient performance. This is achieved by combining a digital current limiter circuit and a traditional voltage-mode control loop. The current-mode control provides a faster response to changes in load and output voltage, while the voltage-mode control helps maintain accurate output voltage regulation.

The VE-23T-IW also features built-in current limit protection, short-circuit protection, thermal shutdown protection, and over-voltage protection. In addition, it is available in a variety of packages, ranging from through-hole to surface-mount types. This makes it suitable for many different application fields including DSPs, CPUs, FPGAs, and embedded systems.

In addition, the VE-23T-IW also has a number of features that make it suitable for applications where low noise is required. These features include a high efficiency of up to 95%, low EMI, and a low ripple voltage noise of 5 mV peak-to-peak. This makes the VE-23T-IW a great choice for applications such as medical devices, high-end audio equipment, and precision measurement systems.

The working principle behind the VE-23T-IW converter is based on a switching regulator circuit. During each cycle, a high frequency switching transistor is turned on and off in order to control the output voltage. This switching transistor is fed by a clock signal which is generated internally. The switching transistor is also connected to an inductor and a series of capacitors, which are used to store and release energy in order to maintain a steady output voltage.

In sum, the VE-23T-IW is an efficient, high current DC/DC converter suitable for a wide range of applications. With its features such as active current limiting, integrated protections, and low noise output, the VE-23T-IW is a great choice for applications where reliability and performance are required. Its switching regulator topology allows it to convert a wide range of input voltages into a precise output, making it a great choice for many different applications.
