Overview

...N 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 combines 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 less than 10 µF with peak-to-peak output ripple as low as 10 mV.
Combined with low-gate charge high-frequency MOSFETs, the Si...
