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