9.1 Application Information

The SN6507 is a transformer driver designed for low-cost, small form-factor, isolated DC/DC converters

using the push-pull topology. The device includes an oscillator that feeds a gate-drive circuit. The gate-drive,

comprising a frequency divider and a break-before-make (BBM) logic, provides two complementary output

signals which alternately turn the two output transistors on and off.
