1. Extremely small footprint High performance and reliability Design flexibility –Easy to use SwitcherPro™ design tool TPS54620 6-A, 17-V SWIFT™ Converter

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
