4.5V to 24V input, 12A continuous, 26A (max) synchronous buck converter

The device is a monolithic, 12A, synchronous buck converter with integrated MOSFETs that enable high efficiency and offer ease-of-use with minimum external component count for space-conscious power systems. The TPS51375 employs D-CAP3 control mode that provides fast transient response and excellent line and load regulation with internal compensation. The ULQ extended battery life feature is extremely beneficial for long battery life in low power operation. The large duty operation greatly improves the load transient performance when input voltage is low.

Other features include differential remote sensing, Eco-mode operation for high light load efficiency, VCC switch-over function for further optimized light load efficiency, and body braking for load transient improvement under low output voltage. TPS51375 supports VCCPRIMVNNAON power rails in Intel Meteor Lake and Arrow Lake platform.

The TPS51375 integrates a power-good indicator and provides an output discharge function. The device provides complete protection, including OVP, UVP, OCP, OTP, and UVLO. The device is available in a 19-pin, 3.0mm × 4.0mm HotRod package, and the junction temperature is specified from –40°C to 125°C.
