4-V to 16-V input, 25-A remote sense synchronous step-down converter

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.
