Product Summary
The 5182QSC is a highly efficient, multiphase, synchronous buck switching regulator controller optimized for converting a 12V main supply into a highcurrent, low-voltage supply for use in point-of-load (POL) applications. It uses a multi-loop PWM architecture to drive the logic-level outputs at a programmable switching frequency that can be optimized for regulator size and efficiency. The applications of the 5182QSC include Auxiliary Supplies, DDR Memory Supplies, Point-of-Load Supplies.
