Introduction
The LMR14010ADDCT is a 2.5A synchronous step-down DC-DC switching regulator integrated with an output stage FET, allowing it to provide an efficient and cost-effective solution for applications such as mobile devices, computer peripherals, and industrial systems. The device features an internal compensation circuit and a high-output voltage accuracy of ±1.5%. It also provides adjustable frequency up to 2MHz, low-noise operation, wide input voltage range, and fixed frequency operation.Application Field
The LMR14010ADDCT is suitable for applications ranging from 5.5V to 32V input and 0.8V to 15V output. It supports an adjustable switching frequency from 0.2MHz to 2MHz, low-noise operation, and very low start-up current. It is specifically designed for simpifying the design of energy-efficient, high-efficiency and high-current power systems. It is ideal for portable systems in outdoor and mobile applications, such as GSM and High Telecom, Point of Sale (POS) terminals, and other industrial systems. Moreover, it can be used in LED driver, printer applications, portable medical equipment and auto systems, LED backlight supplies, server applications, digital monitoring and power distribution systems, power supply design, and so on.It can also be used in smart home applications, automobile systems, digital display equipment and other high power applications.Working Principle
The LMR14010ADDCT integrates a 2.5A internal synchronous step-down DC-DC converter with an output stage FET. It provides adjustable frequency up to 2MHz and a high-output voltage accuracy of ±1.5%. The device features a compact 6x6mm form factor and operates at wide input voltages from 5.5V to 32V. The converter works by using a circuit composed of a pulse-width modulation (PWM) controlled output stage, an input capacitor, an output capacitor, and an inductor. The PWM circuit switches the output stage FET, regulating the output voltage according to the settings of the internal compensation circuit, and transferring energy from the input voltage to the output voltage.The output stage FET also allows internal slope compensation, which optimizes the converter’s dynamic response. The internal switching frequency is adjustable, allowing for different operating frequencies for different load conditions. This further enhances the converter’s dynamic response and efficiency. The device also has built-in short-circuit and over-current protection features, allowing it to operate safely in any condition.Conclusion
The LMR14010ADDCT is a 2.5A synchronous step-down DC-DC switching regulator integrated with an output stage FET. It shows excellent performance, is easily implemented and is supported by a wide range of applications. Its adjustable frequency up to 2MHz, low-noise operation, wide input voltage range, and fixed frequency operation make it an ideal solution for portable and/or high power applications.The specific data is subject to PDF, and the above content is for reference
