DC725A

DC725A is a type of evaluation board from Diodes Inc., designed as a digitally programmable integrated buck converter. It offers design engineers and research technicians specialized solutions to optimize and develop DC/DC and AC/DC applications that require multiple switching topologies. In this article, we will discuss the application fields and working principle of the DC725A assessment device.

Application Field

The DC725A is a digitally programmable buck converter, allowing engineers and technicians to rapidly evaluate switching power solutions in a wide range of DC/DC and AC/DC applications. It offers a maximum output power of 7.2W. The converter is preset to automatically switch between Discontinuous Conduction Mode (DCM) and Continuous Conduction Mode (CCM) in order to maintain a high efficiency rate. Additionally, the device is also capable of being configured to work as a power regulated multi-output converter.

Due to the DC725A’s high efficiency and low power dissipation, its application field ranges from handheld consumer electronic device such as medical instruments, to industrial control systems and stress test equipment.

Working Principle

The DC725A integrated buck converter is capable of being configured to provide constant voltage or constant current. The device is pre-programmed to run and maintain the selected topology. The device runs the selected topology by operating a Pulse Width Modulated (PWM) switching power circuit at a frequency of up to 500kHz. The device is able to maintain a high efficiency rate over the total load range, and is also capable of dynamic phase shifting for reduced EMI and higher efficiency.

The DC725A uses an internal digital controller with integrated synchronous rectification, allowing it to offer a high efficiency over the full load range. It also ensures precise output voltage and current measurements. Additionally, the device is equipped with over-voltage and over-current protection, helping to prevent damage to the device.

Conclusion

The DC725A from Diodes Inc. is a digitally programmable integrated buck converter, designed to be used in a wide range of DC/DC and AC/DC applications. Its capability of switching between DCM and CCM, as well as its high efficiency and low power dissipation, make it a highly suitable device for handheld consumer electronic devices, industrial control systems and stress test equipment. Its pre-programmed PWM switching power circuit and synchronous rectification allow it to offer a high efficiency rate, as well as precise output voltage and current measurements. Its over-voltage and over-current protection ensures the device is protected from potential damage.
