Synchronous buck converter offers ease-of-use for space-conscious power systems

The TPS568215OA 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 it offers ease-of-use with minimal external component count for space-conscious power systems. Key features include a very accurate reference voltage, fast load transient response, Out-of-Audio mode, 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. The device is pin to pin compatible with TPS568215 and TPS56C215 which gives the user flexibility to pick solutions from 6A to 12A in the same footprint.
