SNVS578D – NOVEMBER 2008 – REVISED MAY 2015 LM5037 Dual-Mode PWM Controller With Alternating Outputs
1 Features 3 Description The LM5037 PWM controller contains all the features
necessary to implement balanced double-ended
power converter topologies, such as push-pull, halfbridge 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
device 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 1.2-A peak output current.
The device can be configured to operate directly from
the input voltage rail over a wide range of 13 V to
100 V. 1 High-Voltage (100-V) Start-up Regulator
