Introduction: DC-DC converters are used to convert a DC signal to another DC signal. They are used in a variety of applications, ranging from telecommunications, consumer electronics, automotive, and military/aerospace. The R2D12-0505/HP-R is a high-power DC-DC converter from Rohm Technologies. This converter offers high efficiency and power density in a small package.

Overview: The R2D12-0505/HP-R DC-DC converter is a voltage-mode regulated power supply that uses a synchronous rectification technique to achieve up to 96 percent efficiency. The converter is designed with a turn-on threshold voltage of 2.2 V and a minimum output voltage of 0.75 V. The converter features a maximum switched current of 5 A and a maximum output power of 50 W. It has a wide input voltage range of 2.5 V to 16 V.

Application Field: The R2D12-0505/HP-R converter is suitable for many different applications, including portable medical devices, smart phones, tablet PCs, power brick design, industrial automation, and automotive applications. The converter is also suitable for 5V and 12V battery powered systems. The R2D12-0505/HP-R converter provides a regulated output voltage of 3.3 V, 5 V, 12 V, or multiple adjustable outputs. This makes it ideal for applications such as cameras, phones, routers, notebooks, and tablets.

Working principle: The R2D12-0505/HP-R converter works by converting a DC input voltage to a DC output voltage. It contains two input pins: the input voltage and ground. The input voltage is compared to a reference voltage and the output voltage is set according to this comparison. The output voltage can be controlled by adjusting the reference voltage. To achieve high power conversion efficiency, the converter uses a synchronous rectification technique to switch the output voltage from one polarity to the other.

Protection Features: The R2D12-0505/HP-R converter includes several protection features to ensure safe operation. It has a short-circuit protection function that prevents the output current from exceeding a certain value if a short circuit occurs. It also has an over-current protection and thermal protection features to protect the converter from overloads. The input under-voltage lockout (UVLO) prevents the converter from turning on if the input voltage is below a certain level.

Conclusion: The R2D12-0505/HP-R converter is a high-power DC-DC converter offering high efficiency and power density in a small package. It is suitable for a variety of applications, such as portable medical devices, smart phones, tablet PCs, and power brick designs. It contains several protection features, such as short-circuit protection, over-current protection, and thermal protection, to enable safe and reliable operation.
