The DC/DC converter is a programmable topology
synchronized Buck converter for today’s 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 an input voltage
range of 2.7V to 6V. An additional flexibility is provided with
topology programmability to power multiple loads such as
power amplifiers, microcontrollers, or baseband logic IC’s. For
ultra-high efficiency, converters are designed to operate in
sychronous 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°C to + 85°C.
