DC-DC converters are a key component of modern electronics, wherever a reliable power supply needs to be converted between two voltages. REC3-1205SRW/H2/A/SMD/CTRL-R is one of these devices.

This particular DC-DC converter is an isolated flyback converter, a type of transformer-based regulator. What makes it unique is its incorporation of active switching for voltage control, rather than conventional line frequency control.

This converter has a high power density, making it suitable for use in small, compact electronics. It also has a wide input voltage range, allowing it to be used in applications ranging from 16~90VDC, and an adjustable output voltage, allowing it to be set to between 2.5V and 16V. This makes the REC3-1205SRW/H2/A/SMD/CTRL-R an ideal solution for applications in which a wide range of input voltage is necessary.

In addition, this DC-DC converter has a low ripple voltage, low temperature rise, and low standby power consumption, making it especially appropriate for applications that require higher efficiency.

As for the working principle of the REC3-1205SRW/H2/A/SMD/CTRL-R, it is quite similar to that of other DC-DC converters. It uses the flyback principle, which consists of two main parts: the main switch and the transformer. The main switch is typically a MOSFET. Its voltage is controlled by a pulse width modulation (PWM) signal generated from a control chip. This PWM signal regulates the main switch\'s conducting time, in turn controlling the output voltage of the converter.

The transformer is the other part of the flyback converter. It is composed of two windings, a primary and a secondary. The primary winding is connected to the main switch, and the secondary winding is connected to the output. The transformer is designed in such a way that when the main switch is closed, energy is stored in the magnetic field around the coil. When the main switch is opened, the energy stored in the magnetic field travels towards the secondary winding, and is then converted to a lower voltage, which is regulated by the PWM signal.

The REC3-1205SRW/H2/A/SMD/CTRL-R is thus a highly efficient, compact, and adjustable DC-DC converter, making it suitable for a variety of applications including industrial, consumer, and automotive electronics.
