SN6505BDBVT Description

Short technical summary and product information.

The SN6505BDBVT from Texas Instruments is a specialized power management IC 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 SN6505BDBVT 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 loads.

 

This IC is housed in a compact 6-pin SOT-23 (DBV) package, making it suitable for space-constrained applications. It offers features such as soft start to manage in-rush current, short-circuit protection, and thermal shutdown for enhanced reliability. The operating temperature range is -55°C to 125°C, suitable for demanding environments.
