The TPS549D22 device is a compact single buck converter with
adaptiveon-time, D-CAP3 mode control. It is designed for high
accuracy, high efficiency, fast transientresponse, ease-of-use, low
external component count and space-conscious power systems.
This device features full differential sense, TI integrated FETs
with a high-sideon-resistance of 2.9 mΩ and a low-side
on-resistance of1.2 mΩ. The device also features accurate 0.5%,
0.9-V referencewith an ambient temperature range between –40°C and
+125°C. Competitive features include: very lowexternal component
count, accurate load regulation and line regulation, auto-skip or
FCCMmode operation, and internal soft-start control.
The TPS549D22 device is available in 7-mm × 5-mm, 40-pin,
LQFN-CLIP(RVF) package (RoHs exempt).
