REC6-1212SRW/R8/A/X1 Application Field And Working Principle

Introduction

The REC6-1212SRW/R8/A/X1 is a high quality DC/DC Converter that is designed to transform a source voltage that is between 4.5V and 40V to a rated voltage that is between 3.3V and 35V. It can be employed in a wide range of applications including three-terminal regulators, on-board power systems, and distributed power architectures. This converter is capable of providing up to 12A of output current with an efficiency up to 95%.

Working Principle

The REC6-1212SRW/R8/A/X1 is based on the use of a DMOS transistor. This device is connected between the input voltage of 4.5V to 40V and ground and its duty cycle is controlled by a Pulse Width Modulation (PWM) controller. The DMOS transistor is used to regulate the voltage output.

The PWM controller acts as a switching regulator. It rapidly turns the DMOS transistor on and off and this causes the transistor to switch between the source voltage and ground. This ‘switching’ action creates a varying voltage at the drain of the regulator which is filtered by the built-in filter and sent out to the output of the device.

The PWM controller is capable of varying the ‘duty cycle’ of the switch. This is the ratio of the on-time of the switch to the off-time of the switch. By varying the duty cycle, the output voltage of the converter can be adjusted. It also ensures that the maximum output current is not drawn from the source if the output load is too high.

Applications

REC6-1212SRW/R8/A/X1 converters can be used in a variety of applications including:

• Three-terminal regulators
• On-board power systems
• Distributed power architectures
• Audio amplifiers
• Telecommunications
• Test & measurement equipment
• Automotive electronics
• Networking devices
• Industrial automation

The REC6-1212SRW/R8/A/X1 is an excellent device for providing regulated DC power in a range of applications. Its PWM controller allows it to provide consistent output voltage without drawing excessive input current. This makes it an ideal choice for many different systems.

Conclusion

The REC6-1212SRW/R8/A/X1 is a high quality DC/DC converter designed to provide a regulated output voltage from 4.5 to 40 volts. It employs a DMOS transistor and a PWM controller to regulate the output voltage. The device is capable of providing up to 12A of output current with an efficiency up to 95%. It can be used in a wide range of applications including three-terminal regulators, on-board power systems, audio amplifiers, telecommunications, and more.
