The DC/DC converter is a programmable topology
synchronized Boost converter for today鈥檚 continuous
changing portable electronic market. The DC/DC converter
provides flexibility of utilizing various battery configurations
and chemistries such as NiCd, NiMH, or Li+ with input voltage
range of 2.5V to 6V. An additional flexibility is provided with
topology programmibility to power multiple loads such as
power amplifiers, microcontrollers, or baseband logic IC鈥檚.
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.
The DC/DC converter is available in 20-ports BGA package.
In order to satisfy the stringent ambient temperature
requirements, the DC/DC converter is designed to handle
the industrial temperature range of - 40擄C to + 85擄C.
