3 Description
The TPS54KB2x device is a small, high-efficiency,
synchronous buck converter with an adaptive ontime
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 spaceconstrained
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, Ecomode
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.
