Texas Instruments SN6501 Transformer Driver
for Isolated Power Supplies

Texas Instruments SN6501 Transformer Driver is a monolithic oscillator/power-driver designed for small form factor, isolated power supplies in isolated interface applications. TI SN6501 drives a low-profile, center-tapped transformer primary from a 3.3V or 5V DC power supply. The secondary can be wound to provide any isolated voltage based on transformer turns ratio. SN6501 Transformer Driver consists of an oscillator followed by a gate drive circuit that provides the complementary output signals to drive the ground referenced N-channel power switches. The internal logic ensures break-before-make action between the two switches. This TI device is specified for operation at temperatures from -40°C to 125°C.
