UCC256403DDBR Description

Short technical summary and product information.

The UCC256403DDBR from Texas Instruments is an LLC resonant controller designed for efficient power supply applications. It utilizes a half-bridge topology and incorporates a high-voltage gate driver, simplifying system design.

 

Key electrical specifications include a voltage rating of 600V and a low operating current of 2.2 mA. The controller operates within a temperature range of -40°C to 125°C.

 

This device features hybrid hysteretic control (HHC) for best-in-class transient response and robust adaptive dead-time control. It is optimized for low-power modes and burst mode operation with soft-on and soft-off periods, minimizing audible noise at no load and standby. Efficiency performance exceeds DoE Level VI and EU CoC Tier-2 external power supply standards.

 

The UCC256403DDBR is supplied in a 14-SOIC package, suitable for surface mount applications. It includes integrated protection features such as over-temperature, output over-voltage, input under-voltage protection, and three levels of overcurrent protection.
