The LM5037MT/NOPB is a dual-mode PWM controller designed for balanced double-ended power converter topologies, including push-pull, half-bridge, and full-bridge configurations. It operates over a wide input voltage range of 13V to 100V and features alternating gate drive outputs capable of delivering 1.2A peak output current. The controller supports both current-mode and feed-forward voltage-mode control with minimal external components required. Key features include a programmable maximum duty cycle limit, line under-voltage lockout with adjustable hysteresis, cycle-by-cycle current limit, and a hiccup mode fault protection with an adjustable timeout delay. It also offers a programmable soft-start function, a precision 5V reference output, and a 2 MHz capable oscillator with synchronization capability. The device is housed in a TSSOP-16 package, making it suitable for applications requiring high efficiency and power density.
