TPS54294PWPR

The TPS54294PWPR from Texas Instruments is a dual-channel, synchronous step-down (buck) converter designed for efficient power management. It operates with an input voltage range of 4.5 V to 18 V and provides an adjustable output voltage ranging from 0.76 V to 7.0 V, with a maximum output current of 2 A per channel.

This device features a 700 kHz switching frequency, integrated FETs, and a fixed 1 ms soft-start time. The D-CAP2 control mode ensures fast transient response and compatibility with ceramic output capacitors, requiring no external components for loop compensation. It includes comprehensive protection features such as cycle-by-cycle over-current limit control, OCL/OVP/UVP/UVLO/TSD protections.

The TPS54294PWPR is housed in a 16-pin HTSSOP package, suitable for surface mounting. Its operating temperature range is -40°C to 85°C (TA). This converter is optimized for applications requiring high efficiency, particularly at light loads, with its Auto-Skip Eco-mode.

Key electrical characteristics include a 150 mΩ high-side and 100 mΩ low-side integrated FET resistance, high initial reference accuracy, and loss-less current sensing via the low-side rDS(on). The adaptive gate drivers with integrated boost PMOS switch and thermally compensated rDS(on) contribute to its robust performance.
