Digital Configurable LLC and Multimode PFC Controller

TEA2017AAT Block Diagram

Features

Key Features

  • Complete functionality of LLC and PFC controller in 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
  • Accurate boost voltage regulation
  • PFC can be configured to operate in:
    • DCM/QR (TEA2017ABT)
    • DCM/QR/CCM (also called mixed mode operation) (TEA2017AAT only)
    • CCM fixed frequency (TEA2017AAT only)
  • Integrated X-capacitor discharge without additional external components
  • Power good function
  • PFC jitter for optimized EMI performance
  • Excellent power factor (PF) and total harmonic distortion (THD), as the PFC current compensates for the input filter current
  • 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

  • Valley/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 TEA2017xxT/TEA2095T combination)

Protection Features

  • Independently configurable levels and timers
  • All 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)
  • Inrush current protection (ICP)
  • Brownin/brownout protection
  • Disable input
