The Powereta™ Series offers an industry

 

standard Double-P quarter brick high current 
power module with true useable output 
power. Its 91.5%

 

full load efficiency (92% at 

60A/198W) and superior thermal 
performance make the Powereta™ series of 
power modules ideally suited for tight space 
and power-hungry applications in demanding 
thermal environments.  This rugged building 
block is designed to serve as the core of 
your high reliability system.  A wide output 
voltage trim range, -20 to

 

+10%, and remote 

sensing are standard features enhancing 
versatility.
