DC DC Converters

DC/DC converters are electronic power conversion devices used to convert a source of DC power from one voltage level to another, typically by stepping up or down. These converters regulate and condition power without any significant loss of power in the conversion process. DC/DC converters are used in a wide range of applications, from consumer electronics, industrial automation, automotive, lighting and renewable energy, to military and aerospace.

Additionally, this DC/DC converter is suitable for charging of large-capacity batteries, battery chargers, and motoring operations requiring a wide input voltage range.

The RCQ7572S15 is also suitable for telecommunications equipment such as base station power systems, optical transmission systems, consumer electronics, industrial controls, and other applications.

Working Principle

The RCQ7572S15 utilizes active current mode control, which helps to ensure fast response times and high efficiency. The converter includes a built-in control circuit that provides an output voltage from 0-17V, which can be adjusted according to customer requirements. The full-scale current through the device can be adjusted from 0.01A to 3.0A. The output voltage is regulated within ±1% accuracy under normal conditions and can be modified via a feedback pin.

The RCQ7572S15 can accept input voltages ranging from 4.5V to 72V, and its soft-start feature limits the inrush current to eliminate the need for an external boost diode. The high-frequency switching of the power stage enables the power stage to operate with minimal power losses, allowing the converter to achieve high efficiency.

The integrated protection circuits ensure safe operation and prevent damage from overvoltage, overcurrent, over temperature and undervoltage conditions. Additionally, the RCQ7572S15 includes integrated stable loop control, which ensures better voltage accuracy and faster transient response.
