The TPS544B28 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.

The TPS544B28 device has differential remote sense, high-performance integrated MOSFETs, ±7.5% current telemetry accuracy ≥10A, and supports ±0.5% output voltage accuracy with internal feedback, VOSL = 1 or 0.5, and TJ = 0°C to +85°C. The device features accurate load and line regulation and Eco-mode or Forced Continuous Conduction Mode (FCCM) operation.

The PMBus interface with 1MHz clock support gives a convenient, standardized digital interface for device configuration as well as output voltage, output current, and die temperature telemetry. Pinstrap options allow for the configuration of the overcurrent limit, fault response, internal or external feedback, output voltage selection, and switching frequency. Internal NVM is also available to store a variety of the PMBus parameters.

The TPS544B28 device is a lead-free device. The device is RoHS compliant without exemption.
