VTM48ET120M025A0R DC DC ConvertersDC-DC converters are widely used in industrial, automotive, military, aerospace, medical, and commercial applications to efficiently convert a DC input voltage to a different DC output voltage. VTM48ET120M025A0R is a versatile DC-DC converter from Vicor’s family of isolated converters that provides regulated, low-noise output voltages. The product offers high-efficiency conversion over a wide input voltage range and supports both on-card and on-board installation. It has the ability to provide up to 120 W of small-signal-can output power and 25 A of output current, making it suitable for a wide range of applications. This VTM48ET120M025A0R DC-DC converter has an operating input voltage range between 28 V and 40 V, while the output voltage can be regulated anywhere from 0.8 V to 8 V, in 0.1 V increments. The switch-mode input voltage range for the product is 36 V to 53 V and the maximum temperature for operation is 135°C. The VTM48ET120M025A0R utilizes an insulated metal substrate (IMS) with an integrated heat sink for superior thermal performance. The product includes a built-in EMI filter which reduces the need for external component filtering.The working principle of a VTM48ET120M025A0R DC-DC converter is relatively simple. The input voltage is rectified to a DC voltage and then converted to a higher voltage using an efficient switch-mode converter topology. The DC output voltage is then conditioned by a control circuit, resulting in a regulated output voltage. The efficiency of the converter is usually characterized by the power loss in the switch-mode converter, which is related to the switching frequency and the duty cycle of the power switches used. The VTM48ET120M025A0R is suitable for a wide range of input voltage applications, including telecommunications, industrial, medical, aerospace, automotive, and military. Its small size and rugged construction make it suitable for confined spaces and harsh environments. Moreover, the simplified component count and low-profile topology of the converter makes it an excellent choice for on-board and on-card systems. The device can be used as a point-of-load, motherboard, backplane, and board-level power solution for high-current and/or high-voltage applications.The unique features of the VTM48ET120M025A0R make it an ideal solution for a variety of applications where efficiency, high-current, and small size are important. Its robust construction and ease of installation make it suitable even for the most demanding applications. With its wide input voltage range, efficient operation, and high-current output, the VTM48ET120M025A0R is an ideal DC-DC converter for a broad range of applications.
