The device features a 0.5 MHz typical frequency oscillator and adjustable soft-start/stop time to ensure a smooth operation.

The working principle of the IFX91041EJV33XUMA1 is based on the Pulse Width Modulation (PWM) switching method. It is a two-stage converter, consisting of an output voltage control loop and a feedback loop. The output voltage control loop is responsible for the generation of the PWM signal; it uses the output voltage feedback signal and the duty cycle information to generate the PWM signal. On the other hand, the feedback loop monitors the output voltage and compares it with the reference voltage; an error signal is then generated which is then used to adjust the duty cycle, thereby controlling the output voltage.

The IFX91041EJV33XUMA1 is typically used in computing, automotive and industrial applications. It is suitable for applications that require a wide input voltage range, superior efficiency, a small form factor and low shutdown current. The device is highly reliable and offers superior performance in various operating conditions. The device is also easy to use, making it a preferred choice for many users looking for a reliable and efficient power solution.
