SI9168 General Description
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 to 85.
