Texas Instruments TPS51631ARSMTThe TPS51631A is a driverless step-down controller that is fully compliant with the SVID communications protocol, meeting the Intel VR12.5 specification. Advanced control features such as D-CAP+ architecture with overlapping pulse support undershoot reduction (USR) and overshoot reduction (OSR) provide fast transient response, lowest output capacitance and high efficiency. The TPS51631A also supports single-phase operation in CCM or DCM for light-load efficiency. The TPS51631A integrates the full complement of VR12.5 I/O features including VR_READY (PGOOD),ALERTandVR_HOT. The SVID interface address allows programming from 0 to 7. Adjustable control of VCPU slew rate and voltage positioning round out the VR12.5 features. Paired with the new TPS51604 FET gate driver, the solution delivers exceptionally high speed and low switching loss. The TPS51631A works with selected TI Power Stage™ products for optimum efficiency as well as DrMOS products.
The TPS51631A is available in space saving, thermally enhanced 32-pin QFN package that operates from –40°C to 105°C.
