Si9168
Vishay Siliconix
Synchronous Buck or Boost Controller for 2-Cell Li+ Battery
Operated Portable Communication Devices
DESCRIPTION
FEATURES
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
