The DC/DC converter is a programmable topology
synchronized Buck or Boost converter for today’s continuous
changing 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
for production. Convenient 8-pin plug-in modules are
available for prototyping. 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, with no cooling or derating.
APPLICATIONS (BGA)
•
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

DESCRIPTION
Logic low on SD pin shuts down the FunctionPAK completely and decreases current consumption to less than 1 µA.
Logic high = PWM mode, logic low = PSM mode. In PSM mode synchronous rectification is disabled.
Externally controlled synchronization signal. Logic high to low transition forces the clock synchronization.
If not used the pin must be connected to Vin or logic high.

Included inside the package for all fixed output voltage converters. To be added externally for all self-selected output voltages.
