Texas Instruments TPS548B28 20A Synchronous Buck Converter

Texas Instruments TPS548B28 20A Synchronous Buck Converter comes with an adaptive on-time D-CAP3 control mode. Since external compensation is not required, the device is easy to use and requires few external components. The device is well-suited for space-constrained datacenter applications. TPS548B28 has differential remote sense, high-performance integrated MOSFETs, and an accurate ±1%, 0.6V 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 Texas Instruments TPS548B28 is a lead-free device. It is fully RoHS compliant without exemption.
