The TPS548B23 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 TPS548B23 device has differential remote sense, high-performance integrated MOSFETs, and an accurate ±1.0% internal reference. The device features accurate load and line regulation and Eco-mode or Forced Continous Conduction Mode (FCCM) operation. Pinstrap options allow for configuration of the overcurrent limit, fault response, internal or external feedback , output voltage selection, switching frequency, and soft-start time..

The internal 3.0V LDO can be over-driven with an external 3.3V to 5V supply through the VCC pin to improve efficiency and reduce power dissipation.

The TPS548B23 device is a lead-free device. The device is RoHS compliant without exemption.
