DESCRIPTION
The Si9166 is a programmable topology controller for today’s
continuous changing portable electronic market. Si9166
provides flexibility of utilizing various battery configurations
and chemistries such as NiCd, NiMhy, or Li+ with input
voltage range of 2.7 V to 6 V. An additional flexibility is
provided with topology programmability to power multiple
loads such as power amplifiers, microcontrollers, or baseband
logic IC’s. The converters can be programmed to be
synchronous Buck or Boost topology. 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. All
these features are provided by the Si9166 without sacrificing
system integration requirements of fitting these circuits into
ever demanding smaller and smaller space. The Si9166 is
capable of switching up to 2 MHz to minimize the output
inductor and capacitor size in order to decrease the overall
converter size.
The Si9166 is available in TSSOP-16 pin package and
specified to operate over the industrial temperature range of
-25°C to 85°C.
TYPICAL APPLICATION CIRCUIT
Integrated UVLO and POR
Integrated Soft-Start
