Texas Instruments SN6505ADBVT SN6505ADBVT Transformer Driver 2.25 V to 5.5 in SOT-23-6

The SN6505ADBVT is a low-EMI Push-Pull Transformer Driver, specifically designed for small form factor, isolated power supplies. Ultra-low noise and EMI are achieved by slew rate control of the output switch voltage and through spread spectrum clocking (SSC). The SN6505 consists of an oscillator followed by a gate drive circuit that provides the complementary output signals to drive ground referenced N-channel power switches. The device includes two 1A power-MOSFET switches to ensure start-up under heavy loads. The switching clock can also be provided externally for accurate placement of switcher harmonics or when operating with multiple transformer drivers. The internal protection features include an under-voltage lockout and break-before-make circuitry.
