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 longerrun times, battery status indicationand extended battery life.

– Design for shorter charging timesand “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 placedbetween the source and load to regulatethe voltage and/or current to reduce powerloss.

Every application has different requirements which is why our team has a broad understanding of the best chemistries.
