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 2.7V 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  
sychronous rectified PWM mode under full load while  
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  
• Portable computers  
transforming into externally controlled pulse-skipping mode • Battery back-up supplies  
• Cameras  
(PSM) under light load.
