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 2.5V 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 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°C to + 85°C.
APPLICATION
• Cordless phones, PDAs and others
• Supply voltage source for low-voltage chip sets
• Point of Load (POL) applications such as drivers for
FPGA’s, microprocessors, DSP’s amplifiers, etc.
• Portable computers
• Battery back-up supplies
• Cameras
