MC34904C5EK

MC34904C5EK is a special power management system for embedded electronics, including automotive, industrial, and general-purpose applications. It is part of the larger family of MC34904 products from a well-known brand, Maxim Integrated. The company is known for providing reliable and easy-to-use solutions for power management needs.

Application Field

The MC34904C5EK is designed for applications requiring the highest reliability and performance. It provides excellent efficiency, output voltage and current accuracy, and thermal performance in a compact, integrated system. It is suitable for highly-sophisticated electronics such as automotive infotainment systems, medical equipment, and wireless communication devices. The system can handle power supplies up to 5A with a wide range of standard configurations.

Working Principle

The MC34904C5EK operates by buck-boost, self-powered switching, and pulse-width modulation (PWM). It combines a 4A buck converter and a 5A boost converter on the same die for a total power capability of 9A. The buck converter steps down the input voltage to a desired output, while the boost converter steps it up as required. This combination enables it to efficiently manage power from a wide input range. The system also integrates high-efficiency PWM controllers, temperature compensation and protection circuits.

The MC34904C5EK is designed to provide an ultra-low on-resistance MOSFET to ensure low switching losses and high efficiency. Its frequency-accurate over-current protection and thermal protection circuits allow the power system to operate stably in an active load range. Additionally, its high-efficiency use of current enables it to minimize run times and extend the life of other components.

Conclusion

The MC34904C5EK is an excellent example of specialized power management technology, offering high reliability and performance in a small, integrated system. It provides superior efficiency, output voltage and current accuracy, and thermal performance, suitable for automotive and industrial applications. Its buck-boost, self-powered switching, and PWM capabilities are highly advanced and provide the power system with stable operations over a wide input range. In conclusion, the MC34904C5EK is an excellent choice for power management needs.
