power management chip

Abstract

The invention provides a power management chip, which includes: a phase logic voltage unit, at least three integrated power management units and multifunctional configuration pins. The power management chip is applied to a step-down power conversion circuit. When configured as a parallel output, multiple integrated power management units connected in parallel are controlled by the phase logic voltage unit to supply power for the same load in parallel, wherein each integrated power management unit can also be Configured as an independent working mode, the present invention satisfies the demands of high-power loads by controlling the integrated power management unit in different working modes and different application conditions. In addition, the power management chip has flexible configuration and simple peripheral structure, and can meet the requirements of miniaturization, portability, and lightweight transformation.

Description

Technical field [0001] The present invention relates to the technical field of high power chips, and more particularly to an integrated power management unit of an integrated power management unit. Background technique [0002] With the rapid advancement and development of electronic technology, electronic equipment is moving toward miniaturization, portability, lightweight, and more and more features of electronics, and therefore even more features in order to meet the growing diverse demand. Complex, product consumption is also getting more and more. Now the electronic equipment is moving toward miniaturization, portability, lightweight, and the spatial power management chip space of the electronic system gradually shrinks.

AI Technical Summary

Problems solved by technology

[0003] In traditional ultra-high-power power system applications, the vast majority of high-power power system application solutions are multiple small and medium-power power systems connected in parallel to form an overall power system, which needs to use bus communication with each other, and the system needs an equalization algorithm Or the chip can balance the output current to avoid local overheating. At the same time, because multiple subsystems are connected in parallel, the subsystems will still consume power at light loads. The system may also need a Hall current sensor to monitor the bus current in real time, requiring a microprocessor. Calculate and correct the data of the Hall current sensor to adjust the status and functions of each sub-power system. Local areas cannot obtain the best performance and maximum power output capability, and cannot meet the requirements of electronic equipment for miniaturization, portability, and lightweight transformation of ultra-high-power power supplies
