The LM5037 PWM controller includes all the features to achieve a balanced two-ended power converter topology, push-pull, half-bridge, and full-bridge. These double-ended topologies allow for higher efficiency and greater power density that are more common, such as single-ended flyback, and propose topologies. Voltage mode or current mode control with minimal external components, the LM5037 is configurable. Two alternating gate driver outputs provide the capability of peak output current of 1.2A per A. The LM5037 can be configured directly from a wide range of input voltage rails from 13V to 100V. Other features include programmable maximum duty cycle limit, line undervoltage lockout, cycle-by-cycle current limit, hiccup mode fault protection, adjustable timeout delay, soft-start and 2 MHz synchronization capability, accurate reference and thermal capability oscillator shutdown.
