1 Description
The TPS59610EVM-634 is designed to use a regulated 12-V (8-V to 14-V) bus to produce 10 regulated
outputs for an Atom™ E6xx Tunnel Creek Power System. The TPS59610EVM-634 is specially designed
to demonstrate the TPS59610 Atom E6xx CPU and GPU Vcore regulators while providing a number of
test points to evaluate their static and dynamic performance.
1.1 Typical Applications
• 8-V to 14-V Vin Atom E6xx Tunnel Creek Power System for embedded computing platforms
1.2 Features
The TPS59610EVM-634 features:
• Complete solution for 8-V to 14-V Vin Atom Tunnel Creek Power System
• Selectable 200/300/400/500-kHz switching frequency for CPU and GPU power
• Selectable current limit for CPU and GPU power
• Selectable output overshoot reduction ( OSR™) for CPU and GPU power
• Switches or jumpers for each output enable
• Onboard dynamic load for CPU, GPU Vcore output
• High efficiency and high density by using TI power block MOSFET
• Convenient test points for probing critical waveforms
• Four-layer printed-circuit board with 2 oz of copper on the outside layers
