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