The TPS56C215 is TI’s smallest, monolithic, 12-A synchronous buck converter with an adaptive on-time D-CAP3 control mode. The device integrates low R DS(on) power MOSFETs that enable high efficiency and offers ease-of-use with minimum external component count for space-conscious power systems. Competitive features include a very accurate reference voltage, fast load transient response, auto-skip mode operation for light load efficiency, adjustable current limit and no requirement for external compensation. A forced continuous conduction mode helps meet tight voltage regulation accuracy requirements for performance DSPs and FPGAs. The TPS56C215 is available in a thermally enhanced 18-pin HotRod QFN package and is designed to operate from –40°C to 150°C junction temperature.
