PMIC - Voltage Regulators - DC DC Switching Regulators

The MAX1720EUTG is a Quick-PWM™ DC-DC synchronous step-down converter with an integrated N-channel MOSFET suitable for a 3A continuous load. This high-performance buck converter provides excellent accuracy by using low on-resistance internal MOSFETs, an internal voltage reference, and auto-zero current sensing. It achieves high-efficiency due to its proprietary Quick-PWM architecture, which allows for low-ripple operation and fast transient responses.The MAX1720EUTG has a wide input voltage range of 4.5V to 24V and can operate with switching frequencies up to 500kHz. Its output voltage can be adjusted from 0.6V to 20V with an accuracy of ±3%. The output ripple is typically less than 10mV. Furthermore, the MAX1720EUTG features overcurrent, overvoltage, and thermal protection for safe operation.

Application Fields

The MAX1720EUTG can be used in a variety of applications, such as for powering CPUs and GPUs in desktop and laptop computers, powering FPGAs in communication systems, portable cameras, industrial automation, and motor drives.

Working Principle

The MAX1720EUTG works by regulating the input voltage down to the required output voltage. It does this by switching the input voltage on and off in a specific pattern at a predetermined frequency, called the switching frequency, so that the average output voltage is the desired output voltage.The MAX1720EUTG does this by using an N-channel MOSFET, a voltage reference, and a current sense circuit. First, the voltage reference sets the desired output voltage. Then, the MOSFET switches the input voltage on and off in a specific pattern, while the current sensing circuit controls the amount of current flowing through the MOSFET. The combination of these two circuits results in the desired output voltage and current.The MAX1720EUTG can also adjust the switching frequency to optimize efficiency. The higher the frequency, the faster the output voltage can respond to sudden changes in input voltage, producing faster transient responses and less ripple in the output voltage. The lower the frequency, the lower the power losses due to switching, resulting in increased efficiency.

Conclusion

The MAX1720EUTG is a high-performance buck converter that provides excellent accuracy and high-efficiency thanks to its proprietary Quick-PWM architecture. It is suitable for a variety of applications, from powering CPUs and GPUs in desktop and laptop computers to powering FPGAs in communication systems and motor drives. It features overcurrent, overvoltage, and thermal protection for safe operation and its output voltage can be adjusted from 0.6V to 20V with an accuracy of ±3%.
