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 TPS51388 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.

The EN pin can be used to set Eco-mode or Out-of-Audio (OOA) mode for light-load operation. The Eco-mode maintains high efficiency during light load operation. The OOA mode keeps the switching frequency above audible frequency with minimum reduction in efficiency. The EN pin can be toggled dynamically, even when the converter is in operation.

The TPS51388 integrates a power-good indicator and provides an output discharge function. The TPS51388 provides complete protection including OVP, UVP, OCP, OTP, and UVLO. The device is available in a 13-pin, 3.0mm × 4.0mm HotRod package, and the junction temperature is specified from –20°C to 125°C.
