Isolated Flyback Converter  
with 65V/1.2A Switch  
FEATURES  
DESCRIPTION  
n
2.7V to 42V Input Voltage Range  
The LT®8301 is a micropower isolated flyback converter.  
By sampling the isolated output voltage directly from the  
primary-side flyback waveform, the part requires no third  
winding or opto-isolator for regulation. The output voltage  
is programmed with a single external resistor. Internal  
compensation and soft-start further reduce external com-  
ponent count. Boundary mode operation provides a small  
magnetic solution with excellent load regulation. Low  
ripple Burst Mode operation maintains high efficiency at  
light load while minimizing the output voltage ripple. A  
1.2A, 65V DMOS power switch is integrated along with  
all high voltage circuitry and control logic into a 5-lead  
ThinSOT™ package.

Internal Compensation and Soft-Start  
Output Short-Circuit Protection  
The LT8301 operates from an input voltage range of 2.7V  
to 42V and can deliver up to 6W of isolated output power.  
The high level of integration and the use of boundary  
and low ripple burst modes result in a simple to use, low  
component count, and high efficiency application solution  
for isolated power delivery.
