UCC256403ADDBR Description

Short technical summary and product information.

The Texas Instruments UCC256403ADDBR is an active LLC resonant controller IC offering ultra-low power and ultra-quiet standby operation. It is designed for applications requiring efficient power conversion.

 

Key features include a high voltage gate driver, hybrid hysteretic control, and zero voltage switching capabilities. The device supports optimized low-power modes and burst mode algorithms, minimizing audible noise at no load and standby. It also provides robust adaptive dead-time control and protection features such as over temperature, output over voltage, input undervoltage, and multiple overcurrent protections.

 

This controller operates at 600V with a low operating current of 2.2 mA. It is suitable for resonant converter control and meets efficiency standards like DoE Level VI and EU CoC Tier-2. The device operates within a temperature range of -40°C to 125°C (TA).

 

The UCC256403ADDBR comes in a 14-SOIC package and is designed for surface mount applications. The package dimensions are 9.9 mm x 6 mm, with a total area of 59.4 mm². It is supplied on tape and reel with a standard package quantity of 2500 units.
