What is the REC3-2409SRW/H/B/M/SMD-R?

The REC3-2409SRW/H/B/M/SMD-R DC-DC converter is a type of isolated DC/DC converter designed to produce a regulated output from an unregulated input voltage. It is available in a wide variety of configurations and packages and has a wide range of applications.

Uses of the REC3-2409SRW/H/B/M/SMD-R

The REC3-2409SRW/H/B/M/SMD-R is used to provide regulated outputs in applications where the input voltage may be varying or fluctuating. It is often used to convert a 12V input voltage to a regulated 5V output voltage, or to convert an unregulated +24V input voltage to a regulated +5V output voltage. In addition to its applications in isolated DC/DC converter circuits, it can also be used in DC/DC power supply designs, for example to generate a low-noise 24V power rail from a 48V input.

Technical characteristic of the REC3-2409SRW/H/B/M/SMD-R

The REC3-2409SRW/H/B/M/SMD-R features a wide 4:1 input voltage range: 18V to 75V nominal, with operation over a temperature range of -40°C to +125°C. Its output voltage is adjustable by ±10%, and its output current is limited to 10A max. It offers a wide range of protection features including over-voltage, over-load, short-circuit, and over-temperature protection. It also provides both voltage and current sharing features making it suitable for multi-output applications.

Working Principle of the REC3-2409SRW/H/B/M/SMD-R

The REC3-2409SRW/H/B/M/SMD-R is an isolated DC/DC converter and works in a synchronous buck topology. The input voltage is converted to a high frequency ac (50-100kHz) via the high-side and low-side switching components. The output voltage is maintained by a control loop with a voltage regulation error amplifier. The output voltage is controlled by varying the switching duty cycle of the switches without affecting the input voltage.

Conclusion

The REC3-2409SRW/H/B/M/SMD-R is a versatile DC/DC converter suitable for a wide variety of applications. It features an adjustable output voltage, over-voltage, over-load, and short-circuit protection, plus current sharing capability. It is characterized by its wide 4:1 input voltage range, its tight output voltage regulation, and its high efficiency over a wide temperature range. The REC3-2409SRW/H/B/M/SMD-R is a great choice for isolated DC/DC power supply designs.
