TPS549A20 Synchronous Step-Down SWIFT™ Converter

Texas Instruments TPS549A20 Synchronous Step-Down SWIFT™ Converter is a small-sized (4.50mm x 3.50mm), synchronous buck converter with an adaptive on-time D-CAP3 control mode. The device offers ease-of-use and low bill-of-material count for space-conscious power systems. This converter features high-performance integrated MOSFETs, accurate 0.6V reference, and an integrated boost switch. Competitive features include very low external component count, fast load transient response, auto-skip mode operation, internal soft-start control, and no requirement for compensation. The device also features fault reports via PMBus to simplify the power supply design. A forced continuous conduction mode helps meet tight voltage regulation accuracy requirements for performance DSPs and FPGAs.
