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.
