It is ideal for a wide range of applications such as wireless power systems, LCD display modules, servers and desktop PCs, embedded systems, automotive, digital audio systems and industrial equipment.

Features

The X5043P-2.7A is a highly integrated PMIC that provides a variety of power regulation and monitoring features. It features a wide input voltage range of 2.5V to 15V, with a high-accuracy voltage/current regulation accuracy of ±3%. Additionally, it has a maximum output current of 10A, with an operating temperature range of -40°C to +85°C and a power-on reset delay time of 2ms. It also features a dynamic voltage scaling with a soft-start capability, enabling the user to adjust the output voltage as needed.

Working Principle

The X5043P-2.7A works by taking an input voltage and then regulating it to the desired output voltage level. This is done using a precision voltage reference and a series of feedback and control loops. The voltage reference sets the precision level of the output voltage, while the feedback and control loops monitor the output voltage and adjusts the self-oscillating switching frequency, which is controlled by the Duty Cycle Modulation Controller (DCM). The self-oscillating switching frequency is further adjusted using the Dynamic Voltage Control (DVC) feature, which adjusts the output voltage according to the load current. This helps to achieve high precision, low noise and low power dissipation.

Conclusion

The X5043P-2.7A is a power management integrated circuit that provides an efficient, reliable and accurate power delivery. It is suitable for a wide range of applications that require high-accuracy voltage/current regulation and monitoring. Additionally, it features a variety of features such as dynamic voltage scaling, a wide input voltage range and a high-accuracy voltage regulation accuracy of ±3%. All this helps to make the X5043P-2.7A an attractive choice for any application usage.
