An 8-V to 14-V Vin 2010 Atom™ E6xx
Tunnel Creek Power System
The TPS59610EVM-634 evaluation module (EVM) is a complete solution for the 2010 Atom™ E6xx
Tunnel Creek Power System from a 12-V input bus. The EVM uses the TPS59610 for Atom CPU and
GPU core, TPS51120 for 5-V and 3.3-V systems, TPS54326 for Topcliff IOH, TPS59124 for DDRII 1.8 V
and CPU VTT 1.05 V, TPS51100 for 0.9 V VTT, TPS74801 for CPU 1.5-V PLL, and CPU C6 RAM 1.05 V.
TPS59610EVM-634 also uses the 3-mm x 3-mm Texas Instruments (TI) power block MOSFET
(CSD86330Q3D) for high-power density and superior thermal performance.
