SN6501DBVR -Transformer driver, 3.3V to 5.5V

The SN6501DBVR is a monolithic oscillator/power-driver, specifically designed for small form factor, isolated power supplies in isolated interface applications. The drives a low-profile, center-tapped transformer primary from a 3.3-V or 5-V DC power supply. The secondary can be wound to provide any isolated voltage based on transformer turns ratio.

The SN6501 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.
