Texas Instruments TPS568215 SWIFT Step-Down Converter
Texas Instruments TPS568215 SWIFT™ Step-Down Converter is a small monolithic 8A synchronous buck converter with an adaptive on-time D-CAP3™ control mode. The device integrates low RDS(on) power MOSFETs, enabling high efficiency and ease of use with a minimum external component count for space-conscious power systems. Competitive features include a very accurate reference voltage, fast load transient response, and auto-skip mode operation for light-load efficiency. The Texas Instruments TPS568215 also has an 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.
Features
