Working Principle

The XRP6124ES0.5-F works on a buck topology. It controls the voltage output by varying the on-time of the switch. A PWM comparator triggers and turns the power switch on when the inductor current reaches the set current limit. When the current limit is reached, the PWM comparator turns off the power switch and the inductor current falls down until it is equal to zero. When the current reaches zero, the power switch turns on again, and the process repeats. The XRP6124ES0.5-F has a wide range of features that are designed to improve system performance, such as Temperature Monitoring, Frequency Synchronization, Voltage Regulation and System Power Management. The device also includes a reset generator circuit, which can reset the system at over-voltage detection and under-voltage detection.

Conclusion

The XRP6124ES0.5-F is a high-efficiency, high-power switching controller designed and developed by Rohm Semiconductor. It is widely used in the power management market, digital power and portable power markets. It features adjustable current limit, dual floating outputs, Enable (EN) and Status (ST) pins, frequency synchronization, power-good signal, complete system power control and management, etc. The XRP6124ES0.5-F is suitable for various applications such as voltage conversion, overvoltage protection, microprocessor systems and other computer applications, where high current, high power and high efficiency are essential.
