Texas Instruments TPS51397A 10A Synchronous Buck Converter comes with integrated MOSFETs that enables high efficiency and offers ease-of-use, with minimum external component count for space-conscious power systems. The TPS51397A employs D-CAP3™ control that provides fast transient response and excellent line and load regulation with internal compensation. The ULQ™ (Ultra Low Quiescent) feature is beneficial for long battery life in low power operation. The large duty operation improves the load transient performance when the input voltage is low.
The MODE pin can be used to set Eco-mode™ or Out-of-Audio™ (OOA) mode for light-load operation and 500kHz or 800kHz switching frequency. The Eco-mode™ maintains high efficiency during a light load operation. The OOA mode keeps the switching frequency above audible frequency with minimum reduction in the efficiency. The device supports both internal and external soft-start options. It has an internal fixed soft-start time of 1.2ms. If the application needs a longer soft-start time, the external SS pin can be connected to an external capacitor.
The Texas Instruments TPS51397A integrates a Power Good indicator and provides an output discharge function. It provides complete protection with OVP, UVP, OCP, OTP, and UVLO. The device is available in a 20-pin 3.0mm x 3.0mm HotRod™ package, and the junction temperature is specified from –40°C to 125°C.
