The MPQ8636GLE-4-P is a DC-DC switching regulator from Monolithic Power Systems (MPS) that is used in a variety of applications in industries such as automotive, industrial, aerospace and defense. It is a state-of-the-art 3A integrated power management solution that offers high efficiency, robust protection and fast transient response for switch mode power supplies (SMPS).

The MPQ8636GLE-4-P is designed to be integrated into the end device, which requires few external components, and to provide the power supply stability needed for non-interrupted operation. It features an adjustable 3A current limit, programmable high/low line regulation, adaptive high/low ripple foldback and fast transient response, while maintaining low dropout (LDO) and light load efficiency.

The MPQ8636GLE-4-P switches between two power domains, on and off, and is current mode sensitive. It is able to regulate an output voltage within a specified range given a varying load current. To ensure power supply stability, a voltage loop is employed and a current limit is set by controlling the switching frequency of the device. This is enabled by an internal oscillator along with the error amplifier that provides the current limit and regulation feedback from the output voltage.

The device also includes a power-on reset for fault protection and under-voltage lockout (UVLO) for safe startup and operation. Additionally, an adjustable frequency range of 300kHz-500kHz, an adjustable soft start and an adjustable current limit are also provided in order to achieve the desired performance. The MPQ8636GLE-4-P also features dynamic voltage positioning (DVP) to ensure optimal current sharing in dual-output applications.

The MPQ8636GLE-4-P is well suited for a wide range of applications with versatile features that allow it to be utilized in power supplies for sensors, industrial automation, smart devices, wireless networking and more. It is also suitable for high density applications, such as notebooks and servers, with low power consumption and compact form factor.

In summary, the MPQ8636GLE-4-P is a DC-DC switching regulator from MPS that is suitable for a wide range of applications. It offers an adjustable 3A current limit, programmable high/low line regulation, adaptive high/low ripple foldback and fast transient response, while maintaining low dropout and light load efficiency. It also includes a power-on reset for fault protection and an adjustable frequency range of 300kHz-500kHz, adjustable soft start and adjustable current limit. It is ideal for powering sensors, industrial automation, smart devices, wireless networking and other high density applications.
