DESCRIPTION
The Si9165 provides fully integrated synchronous buck or
boost converter solution for the latest one cell Lithium Ion
cellular phones. Capable of delivering up to 600 mA of output
current at +3.3 V, the Si9165 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 F with peak-to-peak
output ripple as low as 10 mV. Combined with low-gate charge
high-frequency MOSFETs, the Si9165 delivers efficiency up to
95%. The programmable pulse skipping mode maintains this
high efficiency even during the standby and idle modes to
increase overall battery life and talktime. In order to extract the
last ounce of power from the battery, the Si9165 is designed
with 100% duty cycle control for buck mode. With 100% duty
cycle, the Si9165 operates like a saturated linear regulator to
deliver the highest potential output voltage for longer talktime.
The Si9165 is available in both standard and lead (Pb)-free
TSSOP-20 pin packages. In order to satisfy the stringent
ambient temperature requirements, the Si9165 is rated to
handle the industrial temperature range of
25 C to 85 C.
