LTM8049  
Dual SEPIC or Inverting  
µModule DC/DC Converter  
FEATURES  
DESCRIPTION  
TheLTM®8049isaDualSEPIC/InvertingµModule® (power  
module) DC/DC Converter. Each of the two outputs can  
be easily configured as a SEPIC or Inverting converter by  
simplygroundingtheappropriateoutputrail.TheLTM8049  
includes power devices, inductors, control circuitry and  
passive components. All that is needed to complete the  
design are input and output caps, and small resistors to  
set the output voltages and switching frequency. Other  
components may be used to control the soft-start and  
undervoltage lockout.
