The MP8719GQ-P is a series of DC/DC buck regulators that have been designed by Monolithic Power Systems (MPS) specifically for what they call the "point-of-load" (POL) and non-isolated buck conversion market. It provides a cost-effective solution consuming very low output current and produces an output voltage precisely regulated over a wide input voltage range and temperature range. The IC provides an adjustable output voltage, integrated low RDS(ON) power MOSFETs, an over-voltage protection (OVP) circuit, an external current sensing resistor, and an optional external soft start capacitor. The MP8719GQ-P voltage regulator is ideal for high efficiency non-isolated DC/DC conversion applications such as servers, industrial, consumer and telecom applications where precise regulation and low noise operation that guarentees electrical and thermal performance is needed.The MP8719GQ-P’s power handling is especially suited for applications that need precise regulation for a stable output voltage, high efficiency and high power density.

The MP8719GQ-P is classified as a PMIC - Voltage Regulators - DC DC Switching Regulators. It works on the principle of switching regulation. This involves an internal control circuit which senses an output signal to the regulator, compares it to a reference voltage, and then adjusts the duty cycle of the switching cycle to maintain the desired output voltage. This allows the regulator to remain accurate and reliable even as the input voltage, output voltage and current all fluctuate. This is beneficial for applications that require precise voltage regulation for both light and heavy load conditions.

The MP8719GQ-P DC/DC buck regulator features the highest efficiency, lowest output current and a wide input voltage range at up to 75V. It is able to accurately regulate the output voltage from 1.2V-6.0V with tight load and line regulation. The device can handle a maximum output current of 1.2A and a maximum input voltage of 75V. It is protected with over-current, over-temperature and over-voltage protection. The MP8719GQ-P also features an optional adjustable soft start and external current sensing, making it ideal for various applications.

The MP8719GQ-P is well-suited for non-isolated buck conversion applications such as servers, industrial, consumer and telecom applications, where accurate, reliable and low noise operation is essential. In terms of applications, the MP8719GQ-P is ideal for use in high power density applications such as industrial, automotive and communications applications, where a wide input voltage range is needed, as well as for laptop and tablet computers, where precise voltage regulation is necessary.

In conclusion, the MP8719GQ-P is a DC/DC buck regulator from Monolithic Power Systems that is designed for POL and non-isolated buck conversion applications. It works on the principle of switching regulation and has a wide input voltage range, low output current and precise voltage regulation for both light and heavy load conditions. It features integrated low RDS(ON) power MOSFETs, over-voltage protection (OVP) circuit and an external current sensing resistor, making it suitable for various applications. It also offers optional external soft start capacitor and other protection features, making it ideal for high efficiency non-isolated DC/DC conversions.
