TI enables designers to achieve a new low in standby power

11/14/2017

Texas Instruments (TI) introduced a new inductor-inductor-capacitor (LLC) resonant controller with an integrated high-voltage gate driver that enables the industry's lowest standby power, as well as longer system lifetimes. The UCC256301 provides a cost-effective system solution that helps meet stringent energy-efficiency standards for a wide range of AC/DC applications, including digital televisions, gaming adapters, desktop computer and notebook adapters, and power-tool battery chargers.

The first in a family of new high-performance LLC controllers, the UCC256301 enables standby power of less than 40 mW when fully regulating the system output, while also performing better than industry efficiency requirements. By delivering the fastest transient response plus robust fault-protection features such as zero current switching avoidance, the device enables reliable operation over end-equipment lifetimes.

"The consumer electronics market demands efficient power supplies with low standby power. With this new family of LLC controllers, TI is enabling designers to do more with less power," said Steve Lambouses, TI vice president, High Voltage Power. "The UCC256301 was designed to meet tomorrow's power requirements by delivering breakthroughs in standby power and efficiency while simplifying design and lowering system cost."

Key features and benefits of the UCC256301

  • High efficiency and lowest standby power: By achieving a new low in standby power, the controller exceeds Code of Conduct (CoC) Tier 2 and U.S. Department of Energy (DoE) Level VI efficiency standards and achieves more than 90 percent efficiency with a 10 percent load.
  • Faster and more stable system transient performance: Hybrid hysteretic control, a new patented control method from TI, enables up to 10 times faster transient response and reduces output capacitance by 20 percent, leading to faster system response times.
  • Extended system lifetime: Robust fault-protection features on the device, such as zero current switching avoidance, extend system lifetimes.
  • Simplified design: Engineers can easily design their systems with the integrated X-capacitor discharge and high-voltage startup features.
