FEATURES  
DESCRIPTION  
The LTM®8058 is a 2kV AC isolated flyback µModule®  
(micromodule) DC/DC converter with LDO post regulator.  
Includedinthepackagearetheswitchingcontroller,power  
switches, transformer, LDO, and all support components.  
Operating over an input voltage range of 3.1V to 31V, the  
LTM8058supportsanoutputvoltagerangeof2.5Vto13V,  
setbyasingleresistor. Thereisalsoalinearpostregulator  
whose output voltage is adjustable from 1.2V to 12V as  
set by a single resistor. Only output and input capacitors  
are needed to finish the design. Other components may  
be used to control the soft-start control and biasing.
