Complete Switch Mode Power Supply  
The LTM®8047 is an isolated flyback µModule DC/DC  
converter.TheLTM8047hasanisolationratingof725VDC.  
For a similar product with LDO post regulator, see the  
LTM8048. Included in the package are the switching  
controller, power switches, transformer, and all support  
components.Operatingoveraninputvoltagerangeof3.1V  
to 32V, the LTM8047 supports an output voltage range of  
2.5V to 12V, 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.
