DC DC converters are widely used for power conversion, from DC power sources to AC loads. One of the most common forms of DC DC conversion is the REC7.5-1205SRW/H3/A/M.

The REC7.5-1205SRW/H3/A/M is a kind of low noise, high efficiency DC-DC converter module. It is a step-down, non-isolated, synchronous rectifier circuit that operates from 7.5 to 12.5 Volts of input voltage and outputs 5 Volts output voltage with a typical efficiency of 97%. Additionally,it offers over-temperature protection and short circuit protection.

The REC7.5-1205SRW/H3/A/M’s working principle is simple and easy. The power conversion process starts with rectifying the AC input voltage, obtained from a wall power supply, which is then stepped down and voltage regulated using a buck converter. This converter has a high-side switch, inductor, low-side switch, and a Schottky diode.

The high-side switch is controlled by a PWM controller, which periodically pulses on and off the switch, allowing a fraction of the inductor current to go towards the load. The current then flows through the diode and becomes the output current. When the switch closes, the energy stored in the inductor is sent back to the load. Since the PWM frequency is relatively high, the output voltage is maintained very constant. The higher the PWM frequency, the of less ripple in the output voltage.

The REC7.5-1205SRW/H3/A/M is an ideal choice for powering LED lighting projects, instrumentation, and battery charging applications. It is also suitable for medical applications due to its high efficiency and high power density. Moreover, the device features EMI/EMC immunity, providing complete protection against potential interference from external sources.

The REC7.5-1205SRW/H3/A/M is a sharply designed device that offers a wide input voltage range, high step-down conversion ratio, and low standby current. It is a reliable, efficient, and cost-effective choice for a variety of power conversion applications.
