It is suitable for applications from 9V to 45V, making it extremely versatile and suitable for a wide range of applications. The device is ideal for providing regulated power to processors, FPGAs and other digital integrated circuits that require very low noise and low ripple.
Working Principle
The MPQ4560DN-AEC1-LF-Z is a synchronous step-down DC/DC converter. It utilizes a buck topology to achieve high efficiency and low output ripple. The device has an internal controller which works to regulate the output voltage to the desired value. The converter is capable of delivering up to 2.5A of continuous current.
The converter employs a power conversion technique called “pulse-width modulation” (PWM) to obtain high efficiency. In PWM, voltage is converted from the high voltage input to a lower, regulated voltage output by controlling the on and off times of the switch using a controller. This method allows the converter to achieve high efficiency and low ripple while maintaining a small step-size.
The MPQ4560DN-AEC1-LF-Z has excellent transient response characteristics and can provide a fast recovery time to disturbances applied to the input voltage or output voltage, such as a load transient. The device is also able to maintain tight output voltage control under light load conditions for improved system performance.
The device features an adjustable soft-start time which is used to reduce the in-rush current at start-up and helps reduce the stress on external components. Additionally, the device features a built-in oscillator which allows for low EMI and adaptive frequency control for improved system acoustics.
The device also integrated a slew-rate controlled output voltage which reduces the output voltage overshoot for improved system performance.
The MPQ4560DN-AEC1-LF-Z provides excellent power supply design flexibility, with adjustment of output voltage, current limit, soft start, over-voltage protection, under-voltage lockout and so on. Additionally, the device is available in a space-saving, thermally enhanced HTSSOP package.
Conclusion
The MPQ4560DN-AEC1-LF-Z is a synchronous DC/DC converter with a built-in buck controller. It is suitable for applications from 9V to 45V, making it extremely versatile and suitable for a wide range of applications.
