DC-DC converters are a class of power electronics converters that convert a source of direct current (DC) from one voltage to another for a variety of applications. The V375A28T400BS2 is one such DC-DC converter, designed for server-class applications that require efficient and reliable power conversion from 48Vdc to 12Vdc.

Overview

V375A28T400BS2 is a two-stage, non-isolated DC-DC converter. It uses a heavy-duty topology that combines insulation-dependent input voltage regulation with step-down/buck topology. The device is designed to meet or exceed the power requirements of most popular server platforms, including those using Intel processors. V375A28T400BS2 is ideal for applications requiring high efficiency and reliability, such as high-end computing, storage, telecom, medical, broadcast, and industrial.

Detailed Specs

The V375A28T400BS2 has an input voltage range of 40 to 55Vdc. It can deliver a maximum current of 30A with a power efficiency of up to 95%, depending on the input voltage. The device also features built-in over-voltage, over-temperature, and short-circuit protection. The power capability and protection features make it an ideal choice for high-end applications that require tight regulation and reliable performance.

Working Principle

V375A28T400BS2 is designed to follow a flyback topology. This type of topology is known for its low switching losses and high power conversion efficiency. The device works by storing energy on a primary inductor in the primary winding, which is then transferred to the secondary winding via a transformer. This energy is then rectified and regulated to provide a steady output voltage.

Conclusion

The V375A28T400BS2 is an excellent choice for efficient and reliably powering applications that require 48Vdc to 12Vdc conversion. With its high efficiency, wide input voltage range, and protection features, the device can provide reliable, efficient, and clean power to applications with heavy power demands.
