TEA2226AT Digital Configurable LLC Controller

TEA2226

Roll over image to zoom in

The TEA2226AT is a digital configurable controller for high-efficiency resonant power supplies. The power supply is easy to design and has a very low component count. It meets the efficiency regulations of Energy Star, the Department of Energy (DoE), the Eco-design directive of the European Union, the European Code of Conduct, and other guidelines. So, no auxiliary low-power supply is required.

Features

Distinctive Features

  • LLC controller in a single small-size SO16 package
  • Integrated high-voltage start-up
  • Integrated drivers and high-voltage level shifter (LS)
  • High-side driver directly supplied from the low-side driver output
  • Integrated X-capacitor discharge without additional external components
  • Power good function
  • Several parameters can easily be configured during evaluation with use of the graphical user interface (GUI), like:
    • Operating frequencies to be outside the audible area at all operating modes
    • Soft start and soft stop in burst mode, reducing the audible noise
    • Accurate transition levels between operation modes (high-power mode/low-power mode/burst mode)
    • Enabling/disabling the lower power mode

Green Features

  • Zero voltage switching for minimum switching losses
  • Extremely high efficiency from low load to high load
  • Compliant with latest energy-saving standards and directives (Energy Star, EuP)
  • Excellent no-load input power (< 75 mW for TEA2226AT/TEA2095T combination)

Protection Features

  • Independently configurable levels and timers
  • Many protections can independently be set to latched, safe restart, or latched after several attempts to restart
  • Supply undervoltage protection (UVP)
  • Overpower protection (OPP)
  • Internal and external overtemperature protection (OTP)
  • Capacitive mode regulation (CMR)
  • Accurate overvoltage protection (OVP)
  • Overcurrent protection (OCP)
  • Brownin/brownout protection
  • Disable input
  • Input to reset all protections
