1 Description

The TPS59640EVM-751 evaluation module is designed to use a 9-V to 20-V input bus to produce six

regulated outputs for the IMVP-7 SVID CPU/GPU Power System. The TPS59640EVM-751 is specially

designed to demonstrate the TPS59640 full IMVP-7 mobile feature while providing a GUI communication

program and a number of test points to evaluate the static and dynamic performance of the TPS59640.

1.1 Typical Applications

• IMVP-7 Vcore applications for adapter, battery, NVDC, or 3-V/5-V/12-V rails

1.2 Features

The TPS59640EVM-751 features:

• Complete solution for 9-V to 20-V input Intel IMVP-7 SVID Power System

• GUI communication to demonstrate full IMVP-7 mobile feature

• Three-phase CPU Vcore can support up to 94-A output current

• One-Phase GPU Vcore can support up to 33-A output current

• Eight selectable switching frequencies for CPU and GPU power

• Eight levels selectable current limit for CPU and GPU power

• Eight levels selectable output overshoot/undershoot reduction (OSR/USR™) for CPU and GPU power

• Switches or jumpers for each output enable

• Onboard dynamic load for CPU, GPU Vcore and VCCIO output

• High efficiency and high density by using TI power block MOSFET

• Convenient test points for probing critical waveforms

• Eight-layer PCB with 2-oz copper
