SN6505BDBVR Texas Instruments

The SN6505BDBVR Texas Instruments is a low noise, low EMI push-pull transformer driver designed for small form factor isolated power supplies. It drives a flat, center-tapped transformer from a 2.25 V to 5 V DC supply. Ultra-low noise is achieved through slew rate control of the output switch voltage and spread spectrum clocking (SSC).
The SN6505BDBVR consists of an oscillator and a gate drive circuit that provides complementary output signals to drive a referenced N-channel power switch. The device includes two 1A power MOSFET switches to ensure startup under heavy loads. Switching clocks can also be provided externally for accurate placement of switching harmonics.
Protection features of the SN6505BDBVR include 1.7A current limit, undervoltage lockout, thermal shutdown, and break-before-make circuitry. The device also includes a soft-start feature that prevents high inrush currents during power-up using large load capacitors.
