The PSB245-7IR DC DC converter is part of an extensive range of converters designed for use in rugged industrial applications. It is a reliable 1U (3.5”) wide, full-featured DC/DC converter which provides a wide input voltage range of 24V to 75V and a regulated output voltage of 10.2V. It offers selectable current limits and over-temperature protection for extreme environmental operations. The PSB245-7IR provides high efficiency of up to 90%, suitable for a variety of circuits and applications.

The PSB245-7IR is most suitable for high current applications where its high efficiency can help reduce power losses. It is ideal for use in remote antenna amplifiers, air-to-ground communication links, open-loop H bridge inverters, high-power drives, industrial process controllers, and highly reliable micropower converters, and many other industrial environments. The PSB245-7IR is also suitable for powering system clock sources, liquid crystal displays (LCD), or analog to digital converters, and more.

The PSB245-7IR is an isolated DC DC converter, meaning that it is encased in an electrically insulating enclosure so that power from the input side does not affect the output side voltage. Insulation is critically important for protection against induced voltages and currents, as well as dampening the system from electromagnetic interference. The input and output are further isolated by opto-isolators to ensure that the two areas have the same electric ground potential.

The circuit of the PSB245-7IR DC DC converter consists of two MOSFETs in a full bridge configuration with the primary side capable of operating up to 75 V DC and an isolated drive stage controlling a low side switch. The output voltage is determined by a 3 bit digital input, or alternatively by a voltage reference source. An output current limit is also adjusted via discrete and/or pulse width modulation input.

The PSB245-7IR DC DC converter is designed for continuous operation at full load, and can be used for a wide range of input and output voltages. It boasts a wide operating temperature range of -40°C to +85°C, making it suitable for a variety of industrial applications. In addition, it has built-in device protection features such as over temperature protection, over voltage protection and current limiting, which helps to ensure reliable operation.

The PSB245-7IR DC DC converter is a high-performance device designed to provide reliable power for industrial applications in an efficient manner. It offers wide input and output voltage range, high efficiency of up to 90%, selectable current limits, adjustable pulse width modulation, and safe and reliable operation even in extreme environments.
