Specific Solutions
 Our Extensive Experience Includes:
– Reduction of power consumption from the hardware
– Designing the firmware to further reduce power consumption by:
• Turning off unnecessary hardware
• Minimizing the number of times the hardware is accessed
• Reducing the speed of the data being transferred between components
– Implementing simple protectors and analog front ends (AFE’s)
– AC, Inductive and Solar Charging Solutions
– Sophisticated Management and
monitoring electronics for longer
run times, battery status indication
and extended battery life.
– Design for shorter charging times
and “instant-on” operation.

Design is Critical
 Intelligent Power Management Becomes Mandatory
– Today's portable devices can combine wireless communication,
navigation, touch screens and other technologies which require increased
power consumption as:
• The size of the display and the graphics operations of portable devices are
increasing by a large amount.
• New process technologies for the processors operate at higher frequencies.
• Portable devices become smaller and slimmer which requires a reduction of
the number and the size of the components.
• Customers expect extended battery life, so maximum efficiency is essential
• Often the voltage source is “incompatible” with
the load. A buffer needs to be placed
between the source and load to regulate
the voltage and/or current to reduce power
loss.
