DC-DC Converters are widely used in many applications. The REC5-1212SRW/H2/A/SMD/CTRL is one of the latest designs and has a range of applications in the field of power supplies and communication systems. This article will provide information about the application field and working principle of the REC5-1212SRW/H2/A/SMD/CTRL.

The REC5-1212SRW/H2/A/SMD/CTRL is a step-down DC-DC converter. It is a highly efficient two-stage non-isolated DC-DC converter, which provides efficient power conversion from a wide range of input voltage sources. The device uses a synchronous rectifier architecture and a high-frequency switching scheme. It is designed for the high-accuracy start-up, steady-state and light-load performance. The input supply voltage for the converter is 12 to 24 volts DC and the output voltage is controlled by a pulse-width modulation (PWM) signal. The efficiency of the DC-DC converter is 95%, and the total power output is 12.3W.

The REC5-1212SRW/H2/A/SMD/CTRL is primarily used in the power supply and communication systems where low-power and high-accuracy performance is required. It is suitable for use in digital equipment, phones, automotive devices, safety systems and motor control applications. It is also suitable for any application where a steady-state DC output voltage is required. The device has built-in protection features that ensure over-voltage and over-current protection.

The working principle of the REC5-1212SRW/H2/A/SMD/CTRL is based on the use of a synchronous rectifier architecture and a high-frequency switching scheme. The input supply voltage is applied to the input stage (an inductive buck converter) which consists of an inductor, a high-current diode, a sense resistor and a shielded windings. This stage is used to reduce the input voltage to a value that is suitable for the output stage (an isolated buck converter). This stage consists of an output stage module and an integrated controller that monitors the output voltage in order to maintain a precise output voltage level.

The controller contains a pulse-width modulation (PWM) signal generator that produces a low-frequency control signal that determines the duty cycle of the output stage switching. This control signal, in turn, is used to drive the output stage switching elements to control the switching frequency, which is then used to regulate the output voltage. The output voltage is controlled by an external voltage feedback network. The switching confidence and the high-accuracy regulation of the DC-DC converter are ensured by a high-frequency switching scheme.

In conclusion, the REC5-1212SRW/H2/A/SMD/CTRL is a highly efficient two-stage non-isolated DC-DC converter that is suitable for a wide range of applications in the power supply and communication systems. The device is designed for high-accuracy start-up, steady-state and light-load performance and provides excellent protection against over-voltage and over-current conditions. The working principle of the DC-DC converter is based on the synchronous rectifier architecture and high-frequency switching scheme.
