Description
The FAN5182 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 phase relationship of the output signals can...
