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.
