FAN2510S26X is a voltage regulator specifically designed for automotive electronic switch‐mode power supplies. It consists of a low‐dropout (LDO) linear regulator and a DC‐polarity switch. This voltage regulator can regulate 5.0V output voltage over a wide input voltage range of 6.5V to 24V.

Application Field

FAN2510S26X has wide application fields in automotive electronics including radio receivers, DVD players, LCD TVs, rearview cameras, engine control unit, power amplifiers and navigation systems. Its powerful features and capabilities make it ideal for designs with various system voltages.

In addition, because its output current can reach up to 2.6A, it can support high-power automotive electronic components such as car audio systems, power amplifier for speakers, fuel pumps, motor drivers and air conditioning systems. It also includes reverse polarity protection and undervoltage lockout (UVLO) feature, making it an ideal power supply solution for automotive electronic switch‐mode power supplies.

Working Principle

FAN2510S26X operates using a linear regulator along with a DC‐polarity switch. The linear regulator is a type of voltage regulator that maintains an output voltage regardless of changes in the input voltage. The linear regulator seamlessly adjusts the output voltage to varying input voltages, while limiting the voltage range in which the output voltage will be maintained.

The DC‐polarity switch detects the presence of DC power and data signals in automotive electronic switch‐mode power supplies. This switch then sends the DC power and data signal to their respective outputs on the FAN2510S26X voltage regulator. The signal and polarity of the output can then be adjusted accordingly.

The reverse polarity protection and undervoltage lockout (UVLO) feature of the FAN2510S26X voltage regulator will automatically shut down the power supply when negative current is detected or when the input voltage falls below the UVLO threshold. This prevents any accidental and potentially catastrophic electronic component damage in the event of a malfunction.

The FAN2510S26X voltage regulator is a highly efficient voltage regulator ideal for designs with various system voltages. It has the ability to provide reliable, accurate, and safe power supply to automotive electronic switch‐mode power supplies while also protecting the electrical components from harms caused by harmful electrical interference.
