FeaTures  
DescripTion  
n
4.5V to 100V Input Voltage Range  
The LT3512 is a high voltage monolithic switching regula-  
tor specifically designed for the isolated flyback topology.  
No third winding or opto-isolator is required for regula-  
tion as the part senses output voltage directly from the  
primary-side flyback waveform. The device integrates a  
420mA, 150V power switch, high voltage circuitry, and  
control into a high voltage 16-lead MSOP package with  
four leads removed.

BIAS Pin for Internal Bias Supply and Power  
The LT3512 operates from an input voltage range of 4.5V  
to 100V and delivers up to 4.5W of isolated output power.  
Two external resistors and the transformer turns ratio  
easily set the output voltage. Off-the-shelf transformers  
are available for several applications. The high level of  
integrationandtheuseofboundarymodeoperationresults  
in a simple, clean, tightly regulated application solution to  
the traditionally tough problem of isolated power delivery.
