The SN6505ADBVT from Texas Instruments is a specialized integrated circuit designed as a low-noise, low-EMI push-pull transformer driver. It is specifically engineered for creating small form factor, isolated power supplies. This device drives low-profile, center-tapped transformers using a DC power supply ranging from 2.25 V to 5.5 V.
Key features contributing to its low noise and EMI performance include slew rate control of the output switch voltage and spread spectrum clocking. The SN6505ADBVT integrates an oscillator and a gate drive circuit to provide complementary output signals for driving ground-referenced N-channel power switches. It includes two 1-A Power-MOSFET switches, ensuring reliable start-up even under heavy load conditions.
This transformer driver operates within a wide temperature range of -55°C to 125°C and comes in a compact 6-pin SOT-23 (DBV) package, suitable for space-constrained applications. It also incorporates features like soft start to manage in-rush current, short-circuit protection, and thermal shutdown for enhanced robustness.
