• Maximum current 1.5A
• Low profile
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.
APPLICATION
Cordless phones, PDAs and others
Supply voltage source for low-voltage chip sets
Portable computers
Battery back-up supplies
Cameras
Routers
Fiber optics
LANS
Image processing
