The TPS54KB2x device is a small, high-efficiency, synchronous buck converter with an adaptive on-time D-CAP4 control mode. The control method provides low minimum on-time and fast load-transient response across the entire output voltage range without requiring an external compensation network. Because external compensation is not required, the device is easy to use and requires few external components. The device is well-designed for space-constrained data center applications.
The TPS54KB2x device has differential remote sense, high-performance integrated MOSFETs, and an accurate ±0.5% reference over the specified operating junction temperature range. The device features accurate load regulation and line regulation, Eco-mode or FCCM operation, programmable settings through the MSEL pin and programmable soft start.
The TPS54KB2x device is a lead-free device. The device is RoHS compliant without exemption.
