DC DC converters offer a variety of advantages over their AC counterpart, including increased power density, greater efficiency, and lower cost. The REC3-1209SRW/H4/C/SMD is a high-performance non-isolated DC-DC converter that utilizes high-frequency power technologies to eliminate the need for bulky transformers. It offers a power density of up to 30W/in³ and an efficiency of up to 97%.

The REC3-1209SRW/H4/C/SMD DC-DC Converter is designed for applications requiring a wide input voltage range of 4.75V to 18V with a wide temperature range of -40C to +85C. It also offers six output voltages to choose from, including 12V, 15V, 24V, 28V, 36V, and 48V. It is an integrated solution for power system designers, offering open- and short-circuit protection, as well as over-voltage and thermal protection.

The REC3-1209SRW/H4/C/SMD DC-DC converter is suitable for both regulated and non-regulated applications. It provides a constant output voltage with a fast transient response time-downs as fast as 10μs. The built-in EMI filter provides the ability to meet different noise requirements. It also offers two different control modes-dynamic load mode and pulse frequency modulation-to improve output voltage stability.

The working principle of the REC3-1209SRW/H4/C/SMD DC-DC Converter is based on an Active-Clamp forward topology. This topology combines an input section with zero-voltage-switching (ZVS) for high power density, and an output section with active-clamp for high efficiency. The input section rectifies the input voltage and filters it before it passes through the power switch. The filtered signal then passes through an output section which controls the output voltage via the use of an active-clamp. The feedback signal adjusts the duty cycle of the power stage to maintain a constant output voltage.

The REC3-1209SRW/H4/C/SMD DC-DC Converter is ideal for applications requiring a wide voltage range and high power density, such as medical equipment, industrial power supplies, batteries, and automotive systems. It is a highly reliable solution which provides an extremely efficient solution with a wide input and output voltage range, high temperature rating, and strong EMI performance. With these advantages, the REC3-1209SRW/H4/C/SMD is an ideal choice for a wide range of applications.
