The LM25037 PWM controller contains all the features necessaryto implement balanced double-ended power convertertopologies, such as push-pull, half-bridge and full-bridge.These double-ended topologies allow for higher efficienciesand greater power densities compared to common singleendedtopologies such as the flyback and forward. TheLM25037 can be configured for either voltage mode or currentmode control with minimum external components. Two alternatinggate drive outputs are provided, each capable of 1.2Apeak output current. The LM25037 can be configured to operatedirectly from the input voltage rail over an ultra-widerange of 5.5V to 75V. Additional features include programmablemaximum duty cycle limit, line under-voltage lockout,cycle-by-cycle current limit and a hiccup mode faultprotection with adjustable timeout delay, soft-start and a 2MHz capable oscillator with synchronization capability, precisionreference and thermal shutdown.
