DC-DC converters provide a wide variety of applications and are commonly used in power electronics designs. The RP75H-11048SRW/N-HC DC-DC converter is a high-current converter providing power to multiple systems on a single board. It converts input voltage (Vin) from 48V or 75V to a regulated output voltage of 11.0 V / 9.0 A. The converter is designed to meet the most energy efficient and reliable performance requirements for various potential applications.

The RP75H-11048SRW/N-HC converter is a switch-mode power supply featuring a new topology of zero-current switching (ZCS) and zero-voltage switching (ZVS). The converter utilizes a circuit structure which does not need a large inductor to obtain stable operation or provide higher efficiency, and can be made much smaller e.g. by replacing the traditional step-down converter with a circuit built around two phase legs connected in parallel. By utilizing ZCS and ZVS techniques, the converter provides a high degree of protection to the power elements, such as SIPs and FETs, from electrical overstress by providing a continuous monitoring of the power source to avoid direct current leakage and ensure wide DC input operation.All the protection and safety features are integrated in the transmitter, which eliminates the need for external components, giving it the title of "self-protected" converter.

The RP75H-11048SRW/N-HC converter incorporates robust protection features such as input voltage protection (OVP and OCP), current limit protection (OCP) and overload protection, which increase the converter\'s safety and reliability. The converter is also compatible with most standard current mode controllers and is designed to meet applicable medical and telecommunication standards for a wide range of applications. It also provides system designers with some exciting options for integrated solutions from boards with multiple voltage power sources, such as DC-DC converters, bus clock generators, reset drives and pitch controllers.

In operation, the converter uses a high-frequency power switching technique to convert the input signal into the required output voltage. It is a single-input, multiple outputs (SIMO) DC-DC converter with one input voltage and multiple output voltages. It uses ZVS techniques to reduce power losses while the ZCS techniques enable the use of smaller external components, resulting in a small form factor design. In addition, the programmable output current allows users to customize the converter for their target application.

The RP75H-11048SRW/N-HC converter is ideal for applications where efficiency is critical and high-current conversion is needed. The improved on-board diagnostics, built-in safety features and fault monitoring make the application of this converter easy and it can be used in many different type of industrial, medical, automotive, telecoms and consumer electronics applications. It is also easy to integrate within existing products, making it a cost-effective DC-DC converter solution.
