DescriptionThe TPS549B22RVFT device is a compact single buck converter with adaptive on-time, D-CAP3mode control. It is designed for high accuracy, high efficiency, fast transient response,ease-of-use, low external component count and space-conscious power systems.
This device features full differential sense and TI integrated FETs with a high-sideon-resistance of 4.1mΩ and a low-side on-resistance of 1.9 mΩ. The device alsofeatures an accurate 0.5%, 0.9-V reference with an ambient temperature range between –40°C and+125°C. Competitive features include: very low external component count, accurate load regulationand line regulation, auto-skip or FCCM mode operation, and internal soft-start control.
The TPS549B22RVFT device is available in 7 mm × 5 mm, 40-pin, LQFN-CLIP (RVF) package (RoHsexempt).
