Description
General part information
TPS549 Series
The TPS549A20 is a small-sized, synchronous buck converter with anadaptive on-time D-CAP3 control mode. The device offers ease-of-use and low bill-of-material countfor space-conscious power systems.
This device features high-performance integrated MOSFETs, accurate 0.6-V reference, andan integrated boost switch. Competitive features include very-low external-component count, fastload-transient response, auto-skip mode operation, internal soft-start control, and no requirementfor compensation. The device also features fault report viaPMBus to simplify the power supply design
A forced continuous conduction mode helps meet tight voltage regulation accuracyrequirements for performance DSPs and FPGAs. The TPS549A20 is available in a28-pin VQFN-CLIP package and is specified from –40°C to 125°C ambient temperature.
