SN6507/SN6507-Q1 Push-Pull Transformer Driver Texas Instruments SN6507/SN6507-Q1 Low-Emissions 36V Push-Pull Transformer Driver is a high voltage, high-frequency push-pull transformer driver delivering isolated power in a small solution size. The SN6507/SN6507-Q1 implements the benefits of push-pull topology, including simplicity, low EMI, and flux cancellation to prevent transformer saturation. The device achieves further space saving through duty cycle control, which reduces component count for wide-input ranges, and by selecting a high switching frequency, reducing the size of the transformer.
