DC-DC converters are devices that convert direct current from one voltage level to another. R1D10-153.3 is a type of DC-DC converter. It is a high frequency full-bridge switching regulator and DC power source designed to provide the industry’s highest power density and efficiency. It is designed for applications that require an efficient, low profile, and isolated DC-DC power supply.

R1D10-153.3 features an ultra-compact form factor which is about one third of the volume of a traditional switching power supply. It has an excellent thermal performance, which is a result of its clever construction. It is also designed with a wide operating temperature range, from -40°C to +85°C, making it suitable for harsh environments. The device offers up to 90% efficiency and is designed to meet the needs of regulation requirements.

R1D10-153.3 utilises a synchronous rectification circuit combined with highly efficient circuit topology for optimal power performance. It has a high frequency operating frequency of up to 300Khz, enabling it to offer fast transient response performance and a wide input voltage range of 1.5 to 5V. It also features low start-up current of less than 1.5mA, enabling a longer battery life.

The R1D10-153.3 DC-DC converter is ideal for a variety of applications such as distributed point of load (POL) regulation, energy harvesting, motor control, ASICs and FPGAs, and industrial automation. It is also suitable for high power output applications such as high-density computing, servers, medical equipment, aerospace and telecom.

Working principle of R1D10-153.3 is based on the synchronous rectification circuit which allows for very high efficiency. The rectification circuit consists of two high power serially connected MOSFETs, which alternate between conducting and non-conducting states, based on the input and output voltage demands. The output voltage is regulated by the controller IC, which switches the FETs on and off according to the input and output voltage demands.

R1D10-153.3 also has integrated active-clamp reset circuit feature for improved safety, reliability and EMI compliance. The integrated active-clamp reset circuit functions by limiting the output voltage to a safe level by clamping it to the input voltage when the device is in a fault condition. The fault protection circuit of the device is designed to protect against thermal runaway, over-voltage trip, input under-voltage, and over-current conditions.

The R1D10-153.3 is a highly efficient and reliable DC-DC converter capable of providing high power output at an excellent thermal performance. Its high frequency operating frequency allows it to offer fast transient response performance and low start-up current, enabling longer battery life. It also has integrated safety features such as active-clamp reset circuit and fault protection circuit to ensure the device’s reliability.
