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
μF 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 TSSOP-20 pin package. 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.
