The TPS51622A is a driverless, fully SVID compliant, VR12.6 step-down controller. 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 TPS51622A also supports single-phase operation in CCM or DCM for light-load efficiency. The TPS51622A integrates the full complement of VR12.6 I/O features including VR_READY (PGOOD), ALERT and VR_HOT. The SVID interface address allows programming from 0 to 7. In PS4, the quiescent power consumption of controller is typical 0.25 mW. Adjustable control of VCPU slew rate and voltage positioning round out the VR12.6 features. Paired with the new TPS51604 FET gate driver, the solution delivers exceptionally high speed and low switching loss. The TPS51622A works with selected TI Power Stage™ products for optimum efficiency as well as DrMOS products.

The TPS51622A package is a space saving, thermally enhanced 32-pin QFN that operates from –40°C to 105°C.
