Introduction

The XRP7714ILB-0X18-F is an integrated power management integrated circuit (PMIC) from Sumida Corporation, produced and marketed in Japan. It is an external component used for switching power supplies, DC/DC voltage converters, and on-board DC/DC converters. It is also suitable for other applications where high current, fast switching times and high voltage regulation accuracy are required. The XRP7714ILB-0X18-F is categorized as a Linear + Switching PMIC, due to its ability to perform both linear and switching operations.

Application Field

The XRP7714ILB-0X18-F is mainly used in DC/DC voltage converters and switching power supplies. Its high current output rating makes it especially suitable for applications where high power is needed. It is also suitable for applications where fast switching times and high accuracy of voltage regulation are needed, such as measuring and control systems.The XRP7714ILB-0X18-F is designed to perform a range of tasks, including circuit protection, power monitoring, voltage limit setting, current limit setting, current sensing and current feedback control. It can provide a cost effective solution for applications requiring a high level of current output.

Working principle

The XRP7714ILB-0X18-F works by converting an input voltage to the desired output voltage with the help of an internal switching circuit. Depending on the application, the internal switching circuit can be configured to provide either a linear or switching output, which is then fed to the load. The internal switching circuit can be configured to operate in either linear or switching mode. When operating in linear mode, the IC regulates the voltage output by automatically compensating for line and load regulation errors, ensuring a stable and accurate output voltage. When operating in switching mode, the IC works by regulating the voltage output by controlling the pulse-width modulated (PWM) switching of a DC-DC buck converter. When the load current varies, the PWM switching is adjusted and the output voltage is maintained at the desired level.

Conclusion

The XRP7714ILB-0X18-F is an integrated power management IC from Sumida Corporation designed for DC/DC voltage converters and switching power supplies. It is suitable for applications where high current and fast switching times are needed, as well as applications requiring high voltage regulation accuracy. It is classified as a Linear + Switching PMIC and works by converting an input voltage to the desired output voltage with the help of an internal switching circuit, which can be configured to operate in either linear or switching mode. This allows for cost effective solutions where a high level of current output is required.
