SN6505x/SN6505x-Q1 Low-Noise Transformer Drivers

Texas Instruments SN6505x/SN6505x-Q1 Low-Noise Transformer Drivers are low-noise, low-EMI push-pull transformer drivers. They specifically are designed for small form factor, isolated power supplies. Each device can drive a low-profile, center-tapped transformer from a 2.25V to 5V DC power supply. Ultra-low noise and EMI are achieved by slew rate control of the output switch voltage and through Spread Spectrum Clocking (SSC). The SN6505x/SN6505x-Q1 consists of an oscillator followed by a gate drive circuit. This 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 SN6505x-Q1 devices are AEC-Q100 qualified for automotive applications.
