Description
The FAN5182 is a highly efficient, multiphase,
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 provides accurate and reliable over-
current protection and adjustable current limiting.
The FAN5182 is specified over the commercial
temperature range of 0°C to +85°C and is available in a
20-lead Quarter-Size Outline Package (QSOP).
