Transcript of Extremely small footprint High performance and reliability Design flexibility –Easy to use...
• Extremely small footprint
• High performance and reliability
• Design flexibility– Easy to use SwitcherPro™
design tool
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
TPS546204.5V to 17V input 6-A synchronous buck converter
• Integrated Monolithic 26m High Side and 19m Low Side MOSFETs
• 200KHz to 1.6MHz Adjustable Switching Frequency
• 0.8V Reference with 1% Accuracy over Temperature
• Synchronizes to External Clock• Integrated Tracking Function• 3.5 x 3.5mm 14 pin QFN Package
