High Frequency 1-A Synchronous Buck/Boost Converter
DESCRIPTION
The Si9169 provides fully integrated synchronous buck or boost converter solution for the latest one cell Lithium Ion cellular phones. Capable of delivering up to 1 A of output current at + 3.6 V, the Si9169 provides ample power for various baseband circuits as well as for some PAs. It bines the 2 MHz switching controller with fully integrated high-frequency MOSFETs to deliver the smallest and most efficient converter available today. The 2 MHz switching frequency reduces the inductor height to new level of 2 mm and minimizes the output capacitance requirement to...
