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 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.
