IFX1117MEVHTMA1 is a linear voltage regulator integrated circuit (IC) manufactured by Infineon Technologies. This two-channel voltage regulator IC has enhanced specifications and stability compared to earlier voltage regulator ICs. It is designed to operate with input voltages of up to 60 V and output current up to 0.3 A. It is also able to provide superior thermal performance while providing precise control of the output voltage with load and line regulation.

Application Field

The IFX1117MEVHTMA1 is ideal for applications where precise control of the output voltage is required. It can be used in automotive, medical, industrial and general purpose electronic systems for power supply and voltage regulation. It is well suited for CPU power supply, regulator for automotive use, battery chargers, portable applications, and power supplies for industrial, medical and LED lighting.

Working Principle

The IFX1117MEVHTMA1 is a linear voltage regulator that uses the classic feedback technique. It uses an internal error amplifier to compare the output voltage with a reference voltage. Any discrepancy between the two is corrected by adjusting the control pins of the N-channel MOSFET that supplies the output voltage. This control pin can be configured to operate in either continuous or pulse width modulation (PWM) modes.

The IFX1117MEVHTMA1 also features integrated features to improve efficiency and reduce power consumption. It provides thermal shutdown functionality, programmable soft start, and a pulse-by-pulse overcurrent protection. The built-in current limit prevents the MOSFET from current overloads. It also has an internal circuit for reset protection.

In addition to integrated features, IFX1117MEVHTMA1 has enhanced performance specifications compared to its predecessors. It has a high maximum operating temperature of up to 150°C, a wide operating input range of up to 60 V, and high power efficiency of up to 93% at light load conditions. The load regulation is also improved with a maximum output deviation of ±1.5% over the entire output voltage range.

Conclusion

The IFX1117MEVHTMA1 is a linear voltage regulator IC designed to provide precise control of output voltage and load regulation. With its enhanced features and specifications, it is a suitable option for applications that require stable and efficient power regulation. It is also highly reliable and provides high power efficiency at low power levels due to its integrated features.
