直流/直流开关同步降压稳压器, 可调, 1.5V-16V输入, 0.6V-5.5V输出, 40A, LQFN-40
The TPS548D21 device is a compact single buck converter with adaptive on-time, D-CAP3 mode 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, integrated FETs with a high-side on-resistance of 2.9 mΩ and a low-side on-resistance of 1.2 mΩ. The device also features 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 regulation and line regulation, FCCM mode operation, and internal soft-start control.
The TPS548D21 device is available in 5 mm x 7 mm, 40-pin, LQFN-CLIP RVF package RoHs exempt.
