Description

The TPS54JA20 device is a small high-efficiency synchronous buck converter 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 data center applications. The TPS54JA20 device has differential remote sense, high-performance integrated MOSFETs, and an accurate ±1%, 0.9-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 TPS54JA20 device is a lead-free device. It is fully RoHS compliant without exemption. The TPS54JA20 device is a small high-efficiency synchronous buck converter with an adaptive on-time D-CAP3 control mode.
