REC3-1209DRW/H2/A/M/SMD-R

DC DC Converters

The REC3-1209DRW/H2/A/M/SMD-R is a type of DC DC converter, which allows DC signals to be switched between different voltages. It takes in a variable DC input voltage (ranging between 8-20V) and polls an output voltage magnitude of either 3.3V or 5V. It provides a constant output voltage regardless of input voltage changes.The REC3-1209DRW/H2/A/M/SMD-R is an adjustable low dropout regulator, which features 1V low dropout voltage, 3000mA Imax output current, and 8V minimum start voltage. Thus, it is well suited for a wide range of applications, including, but not limited to, personal electronics, computer and communication equipment, medical imaging, LED lighting, and military electronics.

Working Principle

The working principle of the REC3-1209DRW/H2/A/M/SMD-R involves several steps. In the first step, it boosts the input voltage to a higher voltage via an inductor-capacitor (LC) filter. Next, the output voltage is determined by the feedback control circuit, which outputs either a 3.3V or 5V voltage as per the setting. The PWM switching controller controls the switching frequency and duty cycle, allowing the output voltage to remain constant in the face of input voltage changes. In the third step, the output from the switching controller is amplified by the output driver and provided to the switching devices. Finally, the output voltage is filtered by the LC filter to remove any ripple or interference before being provided to the output terminals.

Conclusion

The REC3-1209DRW/H2/A/M/SMD-R DC DC converter is an adjustable low dropout regulator that permits DC signals to be switched between different voltages. Its working principle involves boosting the input voltage through an LC filter, monitoring the output voltage, and using a PWM switching controller to ensure the output voltage remains constant. This converter is well suited for a wide range of applications, making it a viable solution for numerous electronic systems.
