TITPS59650IntelIMVP-7 series processor power solution

TI's TPS51650 and TPS59650 are dual-channel, fully SVID compliant IMVP-7 step-down controllers with two integrated gate drivers. They support CPU and GPU outputs. The CPU path has one, two or three phases, and the GPU path has one or two phases. The 8-bit AC has an output of 0.250V to 1.52V, and the conversion voltage range is 3V to 28V. They are mainly used in IMVP-7 VCORE and adapters, batteries, NVDC or 3V, 5V and 12V power supplies. This article introduces the main features, block diagrams, and multiple typical application circuits of the TPS51650 and TPS59650, as well as the main features and indicators, block diagrams, circuits, bill of materials, and

PCB component layout of the TPS59650EVM-753 evaluation module. (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.
