Si9166
Vishay Siliconix
High Frequency Programmable Topology Controller
DESCRIPTION
FEATURES
The Si9166 is a programmable topology controller for
today’s continuous changing portable electronic market.
Si9166 provides flexibility of utilizing various battery configu-
rations 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 base-
band logic IC’s. The converters can be programmed to be
synchronous Buck or Boost topology. For ultra-high effi-
ciency, 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 both standard and lead (Pb)-free
TSSOP-16 pin packages and specified to operate over the
industrial temperature range of - 25 °C to 85 °C.
