3 Description
The TPS548A20 is a small-sized, synchronous buck
converter with an adaptive on-time D-CAP3 control
mode. The device offers ease-of-use and low bill-ofmaterial
count for space-conscious power systems.
This device features high-performance integrated
MOSFETs, accurate 0.6-V reference, and an
integrated boost switch. Competitive features include
very-low external-component count, fast loadtransient
response, auto-skip mode operation,
internal soft-start control, and no requirement for
compensation.
A forced continuous conduction mode helps meet
tight voltage regulation accuracy requirements for
performance DSPs and FPGAs. The TPS548A20 is
available in a 28-pin VQFN-CLIP package and is
specified from –40°C to 125°C ambient temperature.
