The Si9167 provides a fully integrated synchronous buck
converter solution for the latest 2-cell Lithium Ion battery
cellular phones. Capable of delivering up to 600mA of output
current, the Si9167 provides ample power for various
Baseband circuits as well as for some PAs.
The Si9167 combines the 2-MHz switching frequency 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 a new level
of less than 2 mm and minimizes the output capacitance
requirement to less than 10 F, with only 10-mV peak-to-peak
output ripple.
Combined with its integrated low gate charge high-frequency
MOSFETs and internal synchronous rectifier, the Si9167
delivers efficiency up to 95%. The programmable
pulse-skipping mode maintains high efficiency even during the
standby mode to increase overall battery life and talk time. In
order to extract the last ounce of power from battery, Si9167 is
designed with 100% duty cycle capability for both PSM and
PWM operating modes. With 100% duty cycle, Si9167
operates like a saturated linear regulator to deliver the highest
potential output voltage.
The Si9167 is available in TSSOP-20 pin package. In order to
satisfy the stringent ambient temperature requirements,
Si9167 is specified over the industrial temperature range of
–25 C to 85 C.
