DC DC Converters

DC-DC converters, also referred to as DC-DC transformers, are devices designed to convert direct current (DC) from one voltage level to another. They are used in applications such as computers, cell phones, and car audio systems, among many others.The VI-26T-CW-F2 is a high-efficiency DC DC converter with an input voltage range of 140-265V, and output voltage range of 2-12V. It is suitable for a wide range of applications, from automotive to consumer electronics and power supplies.The VI-26T-CW-F2 is a synchronous step-down converter, with a high switching frequency of 28kHz, and a wide operating temperature range of -40~85℃. The device also incorporates over-voltage protection, under-voltage lockout, and over-temperature protection to ensure reliable operation.The VI-26T-CW-F2 works by controlling the on and off times of the power switch. This creates an output voltage that is lower than the input voltage. The power switch is usually made of a metal oxide semiconductor field effect transistor (MOSFET), and is controlled by the conduction state of the control circuit.The power switch is connected to the primary winding of the transformer, while the secondary winding is connected to the output terminal. When the power switch is ON, the current through the primary winding increases and induces a voltage across the secondary winding which is lower than that of the primary winding. This introduces a voltage transformation, which is the primary purpose of the transformer.The transformer is also used to provide isolation between the input and output voltages. Isolation is important because it prevents ground currents from flowing through the power switch, thus improving immunity to electrical noise.The VI-26T-CW-F2 has a low stand-by power consumption, which is a key benefit for applications that require low power consumption. It also offers high power conversion efficiency, high power factor, and low ripple. These features make the VI-26T-CW-F2 suitable for a wide range of applications such as: LED lighting, household appliance controls, industrial automation, and medical equipment.
