IFX25401TEVATMA1

IFX25401TEVATMA1 is a low drop-out (LDO) voltage regulator device produced by Infineon Technologies. The device belongs to the PMIC – Voltage Regulators – Linear category, and is designed to deliver excellent power performance in a small form factor. With its integrated soft start and slew rate control features, it can easily meet the needs of low noise, fast response power conversion and poly phase support.

The IFX25401TEVATMA1 is a highly integrated, general-purpose voltage regulator offering up to 2A of output current over a wide regulation range of 1.1V to 5.3V. The device incorporates a power MOSFET to provide excellent performance and excellent line and load regulation. It also has an integrated 500mV reference for excellent accuracy, temperature drift and line regulation. This feature-rich device is suitable for a wide range of applications, including portable applications and consumer electronics such as mobile phones and wearable devices.

The device has an internal linear voltage regulator and an external MOSFET to regulate output voltage. It operates in either linear voltage regulation mode or pulse-width modulation (PWM) mode. In the linear mode, a relatively narrow output voltage range is maintained by comparing the error amplifier output to the reference voltage and adjusting the output voltage accordingly. The error amplifier constantly adjusts the output voltage by comparing it to the reference voltage. When the output voltage is lower than the reference voltage, the output voltage is increased to the reference voltage level. When the output voltage is higher than the reference voltage, the output voltage is decreased to the reference voltage level.

In the PWM mode, the device uses the same error amplifier to compare the input voltage to the reference voltage. The PWM signal is generated by a comparator between the error amplifier output and the reference voltage. The PWM signal is then used to control the gate voltage of the MOSFET. The duty cycle of the PWM signal is adjusted dynamically to maintain the output voltage stable at its reference value even when the input voltage is varied.

The IFX25401TEVATMA1 has a wide input voltage range, high power efficiency and low quiescent current consumption, making it ideal for battery-powered systems. It also has an integrated soft start feature, which can be used to reduce in-rush current at start-up. The slew rate control feature is used to ensure an accurate transition from one output voltage to another. The device also offers excellent transient response performance and is protected against over current, overvoltage, and short-circuit conditions.

Overall, the IFX25401TEVATMA1 is an excellent general-purpose LDO regulator device designed to provide high power performance in a small form factor. With its integrated soft start, slew rate control and current limit features, it is a highly reliable solution for many different power conversion applications.
