In summary, the key transformer driver benefits are: simpler and more flexible designs, smaller transformers, reduced EMI, and integrated features. Fewer external components are required, resulting in simpler designs than would be possible ion a non-feedback loop architecture. Greater flexibility is offered because the external transformer winding ratio defines isolated output voltage and allows a selection of flexible isolation voltages. Unlike a flyback, the transformer driver’s forward converter topology does not store the power in the transformer, meaning smaller, lower cost transformers may be used. The transformer driver has reduced EMI due to a consistent 50% switching duty cycle. Integrated features such as spread spectrum, fault detection, overcurrent limiting, and over-temperature protection are also offered with transformer drivers.
