TPS54620 6-A, 17-V SWIFT

1
TPS546206-A, 17-V SWIFT Converter

• Extremely small footprint
• High performance and reliability
• Design flexibility
• Easy to use SwitcherPro design tool

2
Growing trend to reduce DC/DC solution sizes

• Many architectural standards (PCI, ATCA),
  telecom, and server rack equipment have fixed
  shelf/cabinet sizes and power supply budgets
• Increasing PCB density allows designers to
  differentiate their product
• High power efficiency allows increased card
  density and higher product performance
• 12V bus still a popular choice
• Higher current distribution requires smaller
  connectors
• 20W distributed at 12V is 1.6A
• 20W distributed at 3.3V is 6A
• Higher efficiency than 3.3V MOSFET gate drive
  voltage

Greatest need is to increase POL density, without
sacrificing efficiency and performance
