The TPS549A20RVET from Texas Instruments is a high-performance synchronous buck converter designed for efficient power management. It is part of the SWIFT family and features PMBus for digital control and monitoring capabilities.
This device supports a wide input voltage range from 1.5V to 20V, with a bias voltage range of 4.5V to 25V. It can deliver a continuous output current of up to 15A, making it suitable for demanding applications. The output voltage is adjustable from 0.6V to 5.5V, with a reference voltage of 600mV with ±0.5% tolerance from –40°C to 85°C ambient temperature. The switching frequency is selectable, ranging from 200 kHz to 1 MHz via PMBus.
Packaged in a 4.5 mm x 3.5 mm, 28-pin VQFN-CLIP, the TPS549A20RVET is designed for surface mounting. It operates within an ambient temperature range of -40°C to 125°C. Key features include integrated MOSFETs, D-CAP3 control mode for fast load-step response, and various protection mechanisms like hiccup over-current protection.
This converter is well-suited for applications requiring high current density and precise voltage regulation. Its PMBus interface allows for advanced control features such as voltage margin and adjustment, soft-start time, power-on delay, and fault reporting.
