Small synchronous buck converter offers high efficiency and ease-of-use

The TPS568215 is Texas Instruments’ smallest monolithic 8A synchronous buck converter with an adaptive on-time D-CAP3 control mode. The device integrates low RDS(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 device is available in a thermally enhanced 18-pin HotRod QFN package and is designed to operate from –40C to 150C junction temperature. It is pin to pin compatible with TPS56C215 which gives the user flexibility to pick solutions from 6A to 12A in the same footprint.
