The LM25037 PWM controller contains all the 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 singleended
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 5.5V to 75V. Additional features include programmable
maximum duty cycle limit, line under-voltage lockout,
cycle-by-cycle current limit and a hiccup mode fault
protection with adjustable timeout delay, soft-start and a 2
MHz capable oscillator with synchronization capability, precision
reference and thermal shutdown.
