3 Description
The TPS53513 device is a small-sized, synchronous
buck converter with an adaptive on-time D-CAP3
control mode. The device offers ease-of-use and low
external-component count for space-conscious power
systems.
This device features high-performance integrated
MOSFETs, accurate 0.5% 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 (FCCM) helps
meet tight voltage regulation accuracy requirements
for performance DSPs and FPGAs. The TPS53513
device is available in a 28-pin VQFN package and is
specified from –40°C to +85°C ambient temperature.
