Working Principle of the LM5574Q0MTX/NOPB

The LM5574Q0MTX/NOPB is a synchronous step-up/step-down DC/DC regulator that uses pulse width modulation (PWM) for regulating the output voltage. It consists of two MOSFETs for the high and low side and a DC/DC controller to drive them. One of the MOSFETs is turned on to charge the output capacitor, and the other one is turned off to discharge it. When the output voltage reaches the setpoint, the two MOSFETs are alternately turned on and off to maintain the output voltage at the setpoint. The switching frequency of the regulator is adjustable, which allows the user to optimize the efficiency of the converter.

Conclusion

The LM5574Q0MTX/NOPB is an ideal solution for applications requiring an adjustable output voltage range of 0.5V to 25V. Its wide operating range of 9V to 60V makes it suitable for a variety of applications. Additionally, it also offers improved static-phase accuracy and faster operating response, perfect for low-power applications. This makes the LM5574Q0MTX/NOPB an ideal choice for a wide range of DC/DC switching regulator applications.
