DC-DC converters are an integral part of digital and analog circuits, providing efficient power conversion between different voltage levels. REC 5-2405DRW/H4/C/SMD is one such device, offering an integrated input protection and high-profile efficiency for a wide range of applications. This article looks into the device\'s broad range of applications and its working principle.

The REC 5-2405DRW/H4/C/SMD is a DC-DC converter with 4:1 input range. It is a highly efficient and reliable topology with a fixed input range of 18 to 75 Volts, which allows it to be employed in many applications ranging from industrial to automotive. These applications range from motor control applications to the construction of converters, non-isolated regulators and other controlled power supplies. Additionally, a fixed frequency of 100KHz allows for high frequency switching and fast response times, resulting in higher efficiency.

The device also features a wide output range, from 0 to 25 Volts, which offers maximum flexibility for applications that require different levels of voltage. Furthermore, its low quiescent current of 2mA helps in preserving battery power, making it especially suitable for automotive applications. The device also features an integrated input protection circuit for over-current and under-voltage protection. It also has a thermal shutdown feature, which helps in protecting it from damage due to overheating.

The REC 5-2405DRW/H4/C/SMD is available in a variety of packages, including a PowerSMD-8L package, which is especially suited for high density circuits. In terms of performance, it offers an average efficiency up to 85%, with an additional 6mA on output current regulation.

The working principle behind the REC 5-2405DRW/H4/C/SMD is based on a flyback switching topology. The power stage of the device consists of an isolated power transformer, a MOSFET switch, two integrated Schottky diodes and an output inductor. At the moment of the turn-on, current flows through the transformer primary, the MOSFET and the input capacitor, generating a magnetic field that stores energy in the transformer\'s core. When the MOSFET turns off, the stored energy is released and the output voltage is generated, which then gets stored in the output capacitor and delivered to the load.

In conclusion, the REC 5-2405DRW/H4/C/SMD is an efficient and reliable DC-DC converter which offers a high power density, thanks to its wide input voltage range, an integrated input protection circuit and thermal shutdown feature, as well as a wide output voltage range, making it a suitable choice for a variety of applications. Its working principle is based on the flyback switching topology, in which an isolated transformer primary, a MOSFET switch, two integrated Schottky diodes and an output inductor generate an output voltage once the MOSFET turns off. Furthermore, its impressive efficiency of up to 85% and low quiescent current of 2mA make it well suited for many applications, such as motor control, converters and other power supplies.
