SN6505BQDBVTQ1 Description

Short technical summary and product information.

The Texas Instruments SN6505BQDBVTQ1 is a specialized power management integrated circuit designed as a transformer driver for isolated power supplies. It features a wide input voltage range from 2.25 V to 5.5 V and provides a high output drive of 1 A at a 5 V supply.

 

Key electrical characteristics include a switching frequency range of 363 kHz to 517 kHz and a maximum output voltage capability of 16 V. The device also incorporates features such as short-circuit protection, slew-rate control, spread spectrum clocking, and thermal shutdown for robust operation. A typical switch current limit is set at 2 A.

 

This transformer driver is housed in a compact 6-pin SOT-23 (DBV) package, suitable for surface mount applications. It is AEC-Q100 (Grade 1) qualified, making it suitable for automotive applications, and operates within an ambient temperature range of -40°C to 125°C.

 

The SN6505BQDBVTQ1 is designed to reduce conducted and radiated EMI, offering a low-noise solution for power supply designs. Its soft-start feature helps to manage in-rush current during power-up.
