DC/DC converters are a type of power electronics technology which is used to convert a DC input voltage into a regulated DC output voltage. The RI3-1205S/H2 converter is a medium-power DC/DC converter from Recom Power that is designed to provide high efficiency power conversion from a wide input voltage range of 4.5~18 VDC to a single, adjustable, output voltage of up to 12V with a rated load current of up to 5A.

The RI3-1205S/H2 has a number of advantages over other DC/DC converters, including high efficiency up to 86.7% over a wide load range, compact size, low no-load power consumption and good ripple noise specifications. In addition, this converter also features short circuit protection, overload protection and overtemperature protection for enhanced safety and reliability.

The RI3-1205S/H2 is particularly well suited for applications such as industrial automation, control systems, instrumentation, automotive and medical applications. Due to its wide 4.5~18 VDC input range, it can be used in a variety of different types of DC power supplies. It is also suitable for use in battery powered solutions where low standby current and high efficiency are required.

The RI3-1205S/H2 has an easy-to-use fixed frequency PWM control with a minimum on-time of 0.7µs for accurate current and voltage control. It is also a synchronous buck converter, which uses two switching elements to efficiently regulate the output voltage. The two switching elements, an N-channel MOSFET for the high side switch and a P-channel MOSFET for the low side, both have integrated Schottky diodes. This configuration also ensures low RDSON values, resulting in high efficiency.

The RI3-1205S/H2 also features soft start control, which is designed to give a gradual increase in output voltage as the load changes. This ensures that the output voltage remains constant and that there is no sudden increase in current, which could potentially damage sensitive electronic components. In addition, this feature also helps to reduce the risk of electromagnetic interference (EMI).

The RI3-1205S/H2 is a highly reliable and efficient DC/DC converter for a wide variety of applications. It offers excellent features such as high efficiency, wide input voltage range, adjustable output voltage, short circuit protection, overload protection and overtemperature protection, all of which make it particularly well suited for industrial, automotive and medical applications.
