Texas Instruments TPS54KC23 D-CAP4 Synchronous Buck Converter
Texas Instruments TPS54KC23 D-CAP4 Synchronous Buck Converter 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. The device is easy to use and requires few external components because external compensation is not required. The device is well-designed for space-constrained data center applications.
The TPS54KC23 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, line regulation, Eco-mode or FCCM operation, and programmable settings through the MSEL pin and programmable soft start. The Texas Instruments TPS54KC23 device is a lead-free device. The device is RoHS-compliant without exemption.
