This article provides a brief overview of the IFX25001TC V85 and its application fields, along with a description of its working principle.

Application Fields of the IFX25001TC V85

The IFX25001TC V85 is a high-performance, low dropout (LDO) linear voltage regulator that is designed to provide excellent power supply stability, power density, efficiency and thermal management. The device can be used in a wide range of applications, including but not limited to:

• Automotive applications (including 12V and 24V systems)
• Gaming devices
• Notebooks

Working Principle of the IFX25001TC V85

The IFX25001TC V85 uses a linear voltage regulator circuit to control and regulate the output voltage of a power supply. The device includes adjustable output voltage limits and a soft start feature that prevents excessive inrush currents. It also includes current-mode control to ensure stability and protect against over-current, over-voltage and thermal shutdown.The device consists of two transistors (PMOS and NMOS), each of which is connected to a respective resistor. The resistance of each of the resistors is adjusted to set the output voltage. The control signal is then applied to the PMOS transistor, regulating the current across it. The voltage across the output is then also regulated by the PMOS transistor.The output voltage of the IFX25001TC V85 can also be externally controlled, using the voltage divider circuit and adjustable line regulator. The device includes a voltage reference pin, which allows the output voltage to be adjusted with the addition of external components.
