The TPS51650 and TPS59650 are dual-channel, fully SVID compliant IMVP-7 step-down controllers with two integrated gate drivers. 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. All of these controllers also support single-phase operation for light loads. The full compliment of IMVP-7 I/O is integrated into the controllers including dual PGOOD signals, ALERT and VR_HOT. Adjustable control of VCORE slew rate and voltage positioning round out the IMVP-7 features. In addition, the controllers' CPU channel includes two high-current FET gate drivers to drive high-side and low-side N-channel FETs with exceptionally high speed and low switching loss. The TPS51601 driver is used for the third phase of the CPU and the two phases of the GPU channel.

These controllers are packaged in a space-saving, thermally enhanced 48-pin QFN and are rated to operate from –10°C to 105°C.
