•
LM25037-Q1 is an Automotive Grade Product  
that is AEC-Q100 Grade 1 Qualified (-40°C to  
125°C Operating Junction Temperature)  
features necessary to implement balanced double-  
ended power converter topologies, such as push-pull,  
half-bridge and full-bridge. These double-ended  
topologies allow for higher efficiencies and greater  
power densities compared to common single-ended  
topologies such as the flyback and forward. The  
LM25037 can be configured for either voltage mode  
or current mode control with minimum external  
components. Two alternating gate drive outputs are  
provided, each capable of 1.2A peak output current.  
The LM25037 can be configured to operate directly  
from the input voltage rail over an ultra-wide range of
