TPS548B27中文资料具有差分遥感功能的 2.7V 至 16V、20A 同步降压转换器数据手册TI规格书

描述 Description

The TPS548B27 device is a small high-efficiency synchronous buck converter with an adaptive on-time D-CAP3 control mode. Because external compensation is not required, the device is easy-to-use and requires few external components. The device is well-suited for space-constrained data center applications.

The TPS548B27 device has differential remote sense, high-performance integrated MOSFETs, and an accurate ±1%, 0.6-V reference over the full operating junction temperature range. The device features fast load-transient response, accurate load regulation and line regulation, Skip mode or FCCM operation, and programmable soft start.

The TPS548B27 is a lead-free device. It is fully RoHS-compliant without exemption.
