UCC256403DDBT Description

Short technical summary and product information.

The Texas Instruments UCC256403DDBT is a fully featured LLC resonant controller with an integrated high-voltage gate driver. It is designed for applications requiring ultra-low power consumption and ultra-quiet standby operation, exceeding DoE Level VI and EU CoC Tier-2 external power supply standards.

 

Key electrical specifications include a 600V voltage rating and a 2.2 mA current draw. The controller operates within a temperature range of -40°C to 125°C. It offers features such as optimized low-power mode, burst mode with soft-ON and soft-OFF periods, and minimized audible noise at no load and standby.

 

This device is suitable for resonant converter controller applications. It is available in a 14-SOIC package and is designed for surface mount installation. The controller also includes robust adaptive dead-time control and protection features like over-temperature, output over-voltage, input undervoltage, and multiple overcurrent protection levels.
