The Si9168 is a synchronous buck or boost controller for 2-cell
Li+ battery operated portable communication devices.
Designed for use with external high-frequency MOSFETs, the
Si9168 is ideal for providing power to various power amplifiers
such as TDMA, CDMA, GSM, or PCS. For ultra-high efficiency,
converters are designed to operate in synchronous rectified
PWM mode under full load, while transforming into externally
controlled pulse skipping mode (PSM) under light load
conditions. All these features are provided by Si9168 without
sacrificing system integration requirements of fitting these
circuits into ever demanding smaller space. The Si9168 is
capable of switching up to 2 MHz to minimize the size of the
output inductor and capacitor, in order to decrease the overall
converter footprint. The programmability to design a buck or
boost converter with this IC makes it convenient to power
either the high voltage (7.2-V) or low voltage (4-V) PAs.
The Si9168 is available in TSSOP-16 pin package and
specified to operate over the industrial temperature range of
–25 C to 85 C.
