FEATURES
• Specially designed for prototyping in Labs with limited
assembly equipment.
• Fully integrated DC/DC converter
• No external components required
• Buck or Boost configurations
• High efficiency over large load range
• 100% duty cycle
• Power density - more than 570W/inch3
• 1μA shutdown current
• 2.5V to 6V input range (1Li+ and 3-cell NiCd or NiMH cells)
• 0.9V to 6V output voltage
• Programmable PWM/PSM controls
• Low output ripple
• Standard socket construction or plug-in for prototype
(use BGA for production)
• Temperature range: - 40°C to + 85°C
• Output power 15W
• Maximum continuous current 4A
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 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

PIN DESCRIPTION
SD Logic low on SD pin shuts down the FunctionPAK completely and decreases current consumption to less than 1μA.
PWM/PSM Logic high =PWM mode, logic low =PSM mode. In PSM mode synchronous rectification is disabled.
SYNC 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.
Vin Input supply voltage
