The DC/DC converter is

a programmable topology

APPLICATION

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.

• Cordless phones, PDA’s 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

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.
