TPS549D22 SWIFT™ Synchronous Step-Down Converter

Texas Instruments TPS549D22 SWIFT™ Synchronous Step-Down Converter is a compact single buck converter with adaptive on-time, D-CAP3 mode control. This converter is designed for high accuracy, efficiency, fast transient response, ease-of-use, low external component count, and space-conscious power systems. The TPS549D22 features full differential sense, TI integrated FETs with a high-side on-resistance of 2.9mΩ and a low-side on-resistance of 1.2mΩ. The device also features an accurate 0.5%, 0.9V reference with an ambient temperature range between –40°C and 125°C. Competitive features include very low external component count, accurate load and line regulation, auto-skip or FCCM mode operation, and internal soft-start control.
