FEATURES  
DESCRIPTION  
n
Complete Switch Mode Power Supply  
The LTM®8048 is an isolated flyback µModule DC/DC  
converter with LDO post regulator. The LTM8048 has an  
isolation rating of 725VDC. Included in the package are  
theswitchingcontroller, powerswitches, transformer, and  
all support components. Operating over an input voltage  
range of 3.1V to 32V, the LTM8048 supports an output  
voltage range of 2.5V to 13V, set by a single resistor. There  
is also a linear post regulator whose output voltage is ad-  
justable from 1.2V to 12V as set by a single resistor. Only  
output, input, and bypass capacitors are needed to finish  
the design. Other components may be used to control the  
soft-start control and biasing.
