MPQ8636GVE-20-Z , is a product of STMicroelectronics , is a power management integrated circuit (PMIC) with a switching voltage regulator, specifically designed to provide a 3.3V voltage to an application circuit from a 5V source. This device, with its high switching frequency, makes it ideal for all applications requiring a stable regulated voltage with a minimum size.

The MPQ8636GVE-20-Z can be used in a variety of applications, such as data storage systems, CPUs, DSPs, graphics processors, battery chargers, LED drivers, and activity monitors. The device is also suitable for a wide range of automated control applications, including motion control and automation, industrial process and instrumentation applications, and other solutions with high precision requirements.

The device is designed to convert a wide input voltage from 3.3V to 5V with a maximum output current of 15A. The switching frequency can be programmed from 0.15MHz to 3MHz by two external resistors, giving designers flexibility for their application. The device contains an on-chip soft-start feature that limits current inrush during power up and enables smooth start-up of the application.

The MPQ8636GVE-20-Z is a DC-to-DC voltage regulator that uses a switching power converter design. This design relies on a unique combination of power switches and a set of external capacitors that together create alternating high- and low-ratio voltages. In a closed-loop voltage regulator system, an internal error amplifier monitors the input and output voltages, and compares them to determine the correct ratio of low to high voltage levels. The ratio is then adjusted accordingly by the feedback loop to maintain a constant output voltage.

When the output voltage is out of the preset range, the error amplifier closes the loop and adjusts the duty cycle of the voltage regulator to restore the output voltage to the preset level. It does so by bypassing either or both of the power switches. When the duty cycle is increased for a high-supply voltage, the switch is opened and the supply voltage is reduced, reducing the output voltage until it reaches the desired level.

In the case of the MPQ8636GVE-20-Z, the open-loop voltage regulator can be programmed by two external resistors. The characteristic operating frequency is preset to 1MHz, but can be adjusted to a maximum range of 3MHz. Input and output filterings are also provided by an integrated EMI filter and an internal soft-start feature that limits current inrush during power up. Another great feature of the device is the overload protection feature which monitors for any overcurrent conditions in the system and shuts down the regulator.

The MPQ8636GVE-20-Z is a robust DC-to-DC voltage regulator with features specifically designed for modern applications. The high switching frequency and adjustable duty cycle of the product make it ideal for a variety of applications, such as data storage systems, CPUs, DSPs, graphics processors, and more. The device also contains an internal error amplifier, bypass switches, input and output filters, and an overload protection feature. With its wide range of features, the MPQ8636GVE-20-Z is an effective way of providing a stable regulated voltage with a minimum size.
