XC9235A12DER-G Application Field and Working Principle

The XC9235A12DER-G is a high-efficiency, low-dropout Voltage Regulator (LDO) that is used to supplement and stabilize voltage sources within a system. It provides a regulated output at a constant current over a wide range of voltages, which helps protect downstream components from damage due to voltage fluctuations. As a DC DC Switching Regulator, the XC9235A12DER-G is designed to step down an input voltage within a working range of 2.5 to 5.5V, outputting a steady voltage of 1.8V or 2.5V depending on the model used.

The XC9235A12DER-G offers an impressive efficiency of up to 92%, with a minimum dropout voltage of 380mV at a full load with an input of 2.5V. This low dropout voltage and high efficiency makes it a great choice for portable devices, such as smartphones and tablets, where a low power consumption is essential. For use in vehicles, the XC9235A12DER-G is resistant to vibration, shock and corrosion, and the inherently low EMI generated by the device makes it suitable for use in CAN (Controller Area Network) applications.

Working Principles of the XC9235A12DER-G

The XC9235A12DER-G uses a synchronous buck switching regulator as its main component to regulate the output voltage. The synchronous buck converter requires two power switches to convert the input voltage to the output. When the upper switch is turned on, the input voltage is passed to the load. Then, when the lower switch is turned on, the input voltage is connected to the ground and the inductor is used to store energy in the form of magnetic field. Lastly, the stored energy is discharged to the load in order to maintain the output voltage at a constant level.

The main advantage of the XC9235A12DER-G is its high efficiency and wide input voltage range. Compared to traditional linear regulators, the synchronous buck converter allows for much higher efficiency, up to 92%, and wider range of input voltage, down to 2.5V. This makes it suitable for use in many applications such as automotive, consumer electronics and telecommunications.
