Texas Instruments LM25037
The LM25037 PWM controller contains all the features necessary to implement balanced doubleended power converter topologies, such as push-pull, half-bridge and full-bridge. These double-ended topologies allow for higher efficiencies and greater power densities compared to common single-ended topologies such as the flyback and forward. The LM25037 can be configured for either voltage mode or current mode control with minimum external components.| Part No. | LM25037 |
