DC-DC Converters: HPR122C Application Field and Working Principle

DC-DC converters are energy converters which convert one DC voltage level to another. They are universally used in many applications from portable battery powered devices to solar energy storage and distribution. DC-DC converters are used in virtually every electronic device. Among the most prominent of these converters is the HPR122C, a high power, high-efficiency, and low-cost encapsulated DC-DC converter module. The HPR122C is a high power density, reliable, and cost-effective power module.

The HPR122C is a single-phase, synchronous rectification DC-DC converter. It operates at a nominal input voltage of 18-36 VDC, providing a maximum output voltage of 12 VDC and a maximum continuous current rating of 6 A. It has a high power density ratio of up to 8.5W/in3 with a compact design featuring a 30mmx16mm footprint and a 7mm height. There is a wide operating temperature range of -40°C to +85°C, allowing it to perform reliably in extreme environments. The main features of the HPR122C include a high efficiency of up to 95%, low ripple and noise, and a remote sensing, short cycle shutdown, and overcurrent protection. It is also designed for high power bus architectures and includes a 3-way communication connector and a ±10% output voltage trimming capability.

The working principle of the HPR122C lies in its synchronous rectification topology. It is designed to be a compact and energy-efficient power transfer device that reduces the power loss associated with conventional diode rectification. In the synchronous rectification topology, the main switching transistor of the HPR122C acts as a switch that can conduct current both forwards and backwards, enabling it to transfer power across disconnected load lines and to correct any misalignment between the source and load. This rectification is made possible by the use of a specialized full-control integrated circuit.

The HPR122C module has a multitude of potential applications. It is the perfect choice for power supply applications in portable and handheld devices, including mobile phones, consumer electronics, data acquisition systems, industrial controllers, and other low voltage system designs. It is also used in equipment operating in harsh environments such as automotive, marine, and aeronautical applications. Its high power density makes it suitable for use in small scale operations, such as models, toys, and hobby-grade aircraft. Furthermore, its wide operating temperature range and full-control integrated circuit make it suitable for renewable energy applications such as solar and wind turbines.

The HPR122C module is capable of offering reliable, efficient, and cost-effective power transfer in a variety of applications. Its wide range of features, reliable operation, and high power density make it a great choice for power supply needs. With its wide operating temperature range and versatile usage, it is a must-have for any type of power transfer operation.
