Sync Buck for Intel Atom E6xx Tunnel Creek (1.25V @ 10mA)


Design files


TI's Highest Power Density Low Input Voltage Complete Intel Atom E6xx (Tunnel Creek) power system designs; in 967mm2 this design has all the voltage regulators needed to power Intel's Atom E6xx CPU platform and fit onto a 70x70 or smaller COM Express Module used in Industrial Automation and Process Control applications.

  • Voltage Regulators for CPU and  GPU, DDR power, Chipset, RAM, PLL, and CPU Termination rails    
  • CSD86330 power blocks for high efficiency and high power density power solution        
  • Settings for evaluating all Intel IMVP6+ CPU core voltage regulator functions    
  • On-board Load Transient Generator for easy evaluation    
  • 967mm2 total power supply area             
  • Only one 220uF bulk capacitor and five 10uF MLCCs required for CPU and GPU core power
