TPS546206-A, 17-V SWIFT™ Converter

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
