Industry Smallest and Low Profile  
3W 1000mA DC/DC Buck Converter  
with High Output Density Power  
FEATURES  
• Fully integrated DC/DC converter  
• High efficiency over large load range  
• 2MHz switching frequency  
• 100% duty cycle  
• Power density - more than 100W/inch3  
• 1uA shutdown current  
• 2.7V to 6V input range (1Li+ and 3-cell NiCd or NiMH cells)  
• 1.5V to 3.6V output voltage  
• Programmable PWM/PSM controls  
• Low output ripple  
• BGA/LGA construction  
Temperature range: - 40°C to + 85°C  
• No external components needed  
• Output power 3W  
• Maximum current 1.0A  
• Low profile  
The DC/DC converter provides fully integrated synchronous  
buck converter solution for the latest one-cell lithium ion cellular  
phones. Its input voltage is between 2.7V to 6V, capable of  
delivering up to 1000mA of output current at 1.5V to 3.6V.  
The DC/DC converter combines the 2MHz-switching  
controller with fully integrated passive components needed  
to deliver the smallest and most efficient converter available  
today. The high switching frequency minimizes the output  
capacitance with peak to peak output ripple as low as 25mV.  
The DC/DC converter delivers efficiency up to 95%.  
The programmable pulse-skipping mode (PSM) maintains  
this high efficiency even during the standby and idle modes  
to increase overall battery life and talktime. In order to extract  
the last ounce of power from the battery, the DC/DC converter  
is designed with 100% duty cycle control for this mode. This  
function enables the DC/DC converter to operate like a  
saturated linear regulator delivering the highest potential  
output voltage for longer talk time.  
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  
• Battery back-up supplies  
• Cameras  
• Routers  
• Fiber optics  
• LANS  
• Image processing
