DC-DC converters are devices that transform electrical energy from one voltage level to another voltage level. The RP75H-11012SRW/P is one such type of converter. It is a high-voltage, wide-input, ultra-high-efficiency, isolated, synchronous buck-boost DC-DC converter.

The RP75H-11012SRW/P is suitable for applications in the fields of Automotive and Industrial, such as intelligent LED lighting, automotive,industrial control, medical, energy systems, telecommunications, high-power battery management, and unmanned aerial vehicles.

The RP75H-11012SRW/P features a wide input voltage range of 12-75V, up to 98 percent maximum efficiency, high power density of 225W/in3, and a wide 6:1 input to output voltage range. The synchronous buck-boost technology allows for the input voltage to be equal to, higher than, or lower than the regulated output voltage with a single device. In addition, the RP75H-11012SRW/P is housed in a 0.6mm ultra-thin industry standard 22mm x 27.2mm, 4-layer PCB package.

The working principle of the RP75H-11012SRW/P is based on synchronous buck-boost design, which uses two pairs of switching MOSFETs. When the input voltage is higher than the output voltage, the buck switch is on and loads the inductor. When the input voltage is lower than the output voltage, the boost switch is on and loads the inductor. This buck-boost switching mechanism enables step-down and step-up functions with a single operated device.

The design of the RP75H-11012SRW/P ensures a smooth transient response, high efficiency, and temperature stability. The device is equipped with a low-ripple, adaptive on-time control system that accurately determines the optimal inductor current waveform depending on the input voltage and output voltage. This results in a maximum efficiency of 98 percent at 20MHz. Additionally, the device features excellent thermal performance by design thanks to low RDS(on) and low gate charge switches, resulting in the small area for thermal dissipation.

The integrated protection features in the RP75H-11012SRW/P further enhance the performance and reliability of the device. It offers under voltage lockout (UVLO), over-temperature protection (OTP) and over current protection (OCP). These protection features ensure the device is operating within the specified limits and reduces the risk of unexpected device failures.

The RP75H-11012SRW/P is a robust and reliable DC-DC converter ideal for applications in automotive and industrial fields. With wide input voltage, ultra-high efficiency, and excellent protection features, the RP75H-11012SRW/P is the perfect solution for those looking for a reliable and efficient DC-DC converter for their automotive or industrial applications.
