PMIC regulator systems are used across a wide variety of products ranging from portable media and consumer electronics applications, to industrial and space-borne applications. The PMIC regulator systems enable the delivery of high-performance voltage and current regulation in the lowest form factors possible, providing the power efficiency and reliability required by today\'s increasingly complex electronic designs. The MPQ8632GLE-8-P is one such PMIC regulator, part of Maxim Integrated\'s line of voltage regulators commonly used in portable and mobile applications. It is a DC/DC switching regulator, and as such is designed to convert input voltage levels of up to 10 V to output levels in the 0.5 to 6.5 V range.

Maxim MPQ8632GLE-8-P Key Features

The MPQ8632GLE-8-P is a high-efficiency, step-down regulator that integrates two buck switching regulators and an LDO. It is designed to provide as much as 10 A at 0.5 V to 6.5 V from a 10 V input. It features adjustable frequencies up to 1.2 MHz, allowing for small, light, and flexible designs. It is a fully programmable device, with a wide range of switching, current and voltage settings available via an intuitive interface. Other notable features include synchronous rectification, foldback current limit, soft-start, external low-side FET drive and internal compensation.

The device also supports I2C and PMBus programming, so that it can be easily integrated into new designs and system-level applications. It also has an added reset feature that reboots the system when the main power supply is disconnected or lost, preserving system data and preventing system crash. Moreover, its high-efficiency level and low noise operations ensure that system performance is optimized.

MPQ8632GLE-8-P Applications and Working Principle

The MPQ8632GLE-8-P is typically used in power-sensitive applications such as portable equipment, Internet of Things (IoT) devices and wearable electronics. Its design makes it perfect for applications where long battery life, high efficiency levels and low noise operation are essential. It is ideal for applications in the 5 V, 12 V and 24 V input range such as set top boxes, servers, cellular base station, networking routers and switches, and any other mobile or stationary system.

The MPQ8632GLE-8-P is based on a common switching regulator topology. It works by converting its input power into a series of stepped-down voltages. The input voltage is first filtered by an input capacitor and then fed through a voltage divider. The voltage divider sets the output voltage. The voltage is then fed into a switching section, which turns it into a series of pulsed output voltages. An inductor and a capacitor form a filter, which smooths out the output voltages and converts them into a stable output voltage that is suitable for the system load.

The output of the regulator is then fed through an output filter to remove any residual noise. Finally, an output voltage regulator is used to control the output voltage to the desired level. All of this is accomplished through the use of an on-board controller chip, which monitors the system and ensures that the output voltage is at the desired level. It is also responsible for adjusting the frequency of the switching for optimal efficiency.

Conclusion

The MPQ8632GLE-8-P from Maxim Integrated is a high-efficiency, step-down regulator that is suitable for battery-powered applications, where reliability, high efficiency and low noise operation are essential. It is designed to convert an input voltage of up to 10 V to an output voltage of 0.5 to 6.5 V and supports I2C and PMBus programming. The MPQ8632GLE-8-P is a DC/DC switching regulator, based on a common switching regulator topology, and is a perfect solution for any number of power-sensitive applications.
