The SN6505 is a low-noise, low-EMI push-pulltransformer driver, specifically designed for smallform factor, isolated power supplies. It drives low profile,center-tapped transformers from a 2.25 V to5 V DC power supply. Ultra-low noise and EMI areachieved by slew rate control of the output switchvoltage and through Spread Spectrum Clocking(SSC). The SN6505 consists of an oscillator followedby a gate drive circuit that provides the complementary output signals to drive ground referenced N-channel power switches. The device includes two 1-A 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 a 1.7A current limiting, under-voltage lockout, thermal shutdown, and break-before-make circuitry. SN6505 includes a soft-start feature that prevents high inrush current during power up with large load capacitors. The SN6505 is available in a small 6-pin SOT23/DBV package. The device operation is characterized for a temperature range from –55°C to 125°C.
