Description

The FAN5182 is a highly efficient multi-phase synchronous buck switching regulator controller optimized for converting a 12V main supply into a high-current 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 be programmed to provide 1, 2, or 3-phase operation, allowing for construction of up to three complementary interleaved buck switching stages.

The FAN5182 also provides accurate and reliable over-current protection and adjustable current limiting.

FAN5182 is specified over the commercial temperature range of 0°C to +85°C and is available in a 20-lead QSOP package.
