The TPS56C215 is TI’s smallest monolithic 12-A synchronous buck converter with anadaptive on-time D-CAP3? control mode. The device integrates lowRDS(on) power MOSFETs that enable high efficiency and offers ease-of-usewith minimum external component count for space-conscious power systems. Competitive featuresinclude a very accurate reference voltage, fast load transient response, auto-skip mode operationfor light load efficiency, adjustable current limit and no requirement for external compensation. Aforced continuous conduction mode helps meet tight voltage regulation accuracy requirements forperformance DSPs and FPGAs. The TPS56C215 is available in a thermally enhanced 18-pinHotRod? QFN package and is designed to operate from –40°C to 150°Cjunction temperature.
