DC DC Converters: R1D10-1209

DC DC converters are circuits in which direct current from a source of electricity is converted to a different direct current voltage for use in various applications. The R1D10-1209 DC DC converter is a switching regulator power supply that produces an output voltage and can be connected as part of a circuit or to provide power directly to specific electronic components. This converter is capable of producing an output voltage of 9V to 12V and can handle a maximum current of up to 1.4A. It is a high efficiency, low power draw converter that is suitable for a variety of applications.

Application Field

The R1D10-1209 DC DC converter is ideal for use in automotive electronic systems, including remote opening systems, computer displays, and audio equipment. It can also be used in many other applications, such as test equipment, medical and laboratory equipment, hobby robots, and power supplies for general-purpose electronic circuits.

Working Principle

The R1D10-1209 DC DC converter operates by taking an input voltage of 3.5V to 36V, which can be either from a battery or an AC adapter, and converting it to an adjustable output voltage of 9V to 12V. This is achieved through an integrated high-precision pulse width modulation (PWM) controller that regulates the voltage output. The converter utilizes a Constant-On-Time (COT) Foldback design with synchronous rectification technology to ensure a high power efficiency and a low standby current. The output voltage can be adjusted by changing the value of an external potentiometer, and the output current is limited to 1.4A by current limiting circuitry. To further protect the device, the converter also includes over temperature and over current protection.

Conclusion

The R1D10-1209 DC DC converter is a robust and cost-effective power solution for a variety of applications, from automotive electronics to general-purpose equipment. Thanks to its adjustable output voltage and the COT Foldback design, it is capable of providing a steady output with low standby current and high efficiency. Furthermore, a built-in circuit protects the device from over current and over temperature conditions.
