Resonant Power Supply Control IC



Distinctive Features

  • Complete functionality as a combination with TEA19162T
  • Integrated high-voltage start-up
  • Integrated high-voltage level shifter (LS)
  • Very fast start-up (< 500 ms at Vmains = 100 V (AC))
  • Continuously VSUPIC regulation via the SUPHV pin during start-up and protection, allowing minimum SUPIC capacitor values
  • Operating frequencies are outside the audible area at all operating modes
  • Integrated soft start
  • Powergood function
  • Maximum 500 kHz half-bridge switching frequency

Green Features

  • Very high efficiency from low load to high load
  • Compliant with energy using product directive (EuP) lot 6
  • Excellent no-load input power (< 75 mW for TEA19161T/TEA19162T/TEA1995T combination)
  • Regulated low opto current, enabling low no-load power consumption
  • Very low supply current during non-switching state in burst mode
  • Adaptive non-overlap time

Protection Features

  • Supply undervoltage protection (UVP)
  • Adjustable latch or restart function for overpower protection (OPP)
  • On-chip overtemperature protection (OTP)
  • Capacitive mode regulation (CMR)
  • Accurate overvoltage protection (OVP)
  • Maximum on-time protection for low-side and high-side driver output
  • Overcurrent protection (OCP)
