Introduction

The MPQ8636HGL-10-Z is a DC-DC switching regulator from the PMIC (Power Management IC) series. It is a type of voltage regulator, which is used to produce a steady and consistent voltage for various applications. This type of device is most commonly used when a voltage source is needed for electrical devices that require a specific voltage for optimal performance.The MPQ8636HGL-10-Z is a fully integrated dual linear and switching regulator. It features an internal step-up/step-down topology and also includes an internal low-dropout linear regulator. This makes it highly versatile and capable of providing reliable power to multiple components with a single device.

Application Field

The MPQ8636HGL-10-Z is primarily used in power supplies, chargers, and other power applications where the primary source needs to be regulated. This device is especially popular in telecommunications and embedded systems, as it is capable of providing precise voltage regulation with minimal power consumption. It is also used in a variety of other electronic applications, such as medical equipment, automotive applications, and industrial control systems.

Working Principle

The MPQ8636HGL-10-Z utilizes a maximum peak current mode control scheme. This scheme is designed to monitor the peak current, rather than the average current, in order to provide better dynamic response to load changes and also to minimize output voltage overshoot.The device also has an internal slow start circuit and an under voltage protection circuit. The slow start circuit gradually increases the output current in order to reduce the inrush current and minimize transient disturbances. The under voltage protection circuit monitors the VIN (input voltage) pin and will shut off the device if the voltage drops below a preset threshold.

Conclusion

The MPQ8636HGL-10-Z from the PMIC series is a versatile dual linear and switching regulator that is capable of providing a precise and steady output voltage for numerous applications. It features an internal step-up/step-down topology, a slow start circuit, an under voltage protection circuit, and a maximum peak current mode control scheme. These features make it an ideal device for use in power supplies, chargers, and other power or telecommunication applications where precise voltage regulation is needed.
