DC-DC converters are an important component of any electronic system, which converts a given DC input signal to an appropriate DC output signal. The VI-260-CW is a DC-DC switching converter commonly used in mobile, embedded, and automotive applications for power regulation, sensing, and protection. This article will explain the application field and working principle of the VI-260-CW.

The VI-260-CW is a high efficiency, high powered DC-DC converter with a wide range of input/output voltages, current handling capacity, and temperature range. It is suitable for powering loads in the range of 2.5 to 36V, and is well suited for applications such as microcontrollers, RFID systems, POE systems, and commercial products. The VI-260-CW is also capable of providing temperature tracking for temperature-sensitive applications. Additionally, it has a very low quiescent current of 8mV, making it an ideal choice for battery operated devices.

The VI-260-CW offers a wide range of protection features such as over-voltage protection (OV protection), short-circuit protection (SCP protection), and transient protection. The OV protection prevents the input voltage from exceeding its limits and thus protects the circuit and device from damage. SCP protection prevents any current overloads and increases the life of the device. Transient protection prevents short-term shocks or spikes which can damage the circuit or device. Total harmonic distortion is also kept to the minimum, making it highly suitable for powering precision electronics. Moreover, the VI-260-CW has a rated input voltage of 18 – 36V, making it ideal for a wide variety of power sources.

Moving on to the working principle of the VI-260-CW, it uses a full H-bridge power conversion stage, consisting of a high side and low side MOSFETs, a Schmitt trigger inverting circuit, an inductor, a PWM controller, and an opto-isolator. When a DC input is applied to the converter, the Schmitt trigger circuit activates the H-bridge power circuit. The inductor stores energy and the MOSFETs direct the power into the required direction at the output. The PWM controller regulates the speed with which the power is delivered. The opto-isolator provides isolation between the power input side and the output side of the converter. The VI-260-CW is a highly efficient and powerful converter with many safety features. It is suitable for a wide range of applications due to its wide range of input/output voltages and its temperature tracking capability. The VI-260-CW uses an H-bridge power conversion stage for efficient power delivery, and has a very low quiescent current, making it ideal for battery operated devices. With its high performance, safety features, and wide range of input/output voltages, the VI-260-CW is an ideal choice for powering loads in both mobile and embedded applications.
