At the high end you shrink the transformer core and output capacitor, but you trade off switching losses and snubber dissipation. The 80% maximum duty cycle is typical for flyback designs — it gives enough on-time for step-up ratios without starving the transformer reset. If your design needs a duty cycle above 80%, you are looking at a different topology or a controller with a wider pulse-width window. ## Lifecycle and sourcing The MAX5974DETE+T carries an Active lifecycle status with ROHS3 compliance.","metaTitle":"MAX5974DETE+T Switching Controller, Flyback/Forward","metaDescription":"MAX5974DETE+T step-up/step-down PWM controller for flyback/forward converters. 8.4V–26V supply, 80% max duty, clock sync, synchronous rectifier.
