Description for the TPS549D22
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).
