TEA1611T

Zero-voltage-switching resonant LLC controller, extended feature set


The TEA1611T is a monolithic integrated circuit implemented in a high voltage Diffusion Metal Oxide Semiconductor (DMOS) process, which is a high voltage controller for a zero voltage switching resonant converter. The IC provides the drive function for two discrete power MOSFETs in a half-bridge configuration. It also includes a level-shift circuit, an oscillator with accurately programmable frequency range, a latched shut-down function and a transconductance error amplifier.

Features and benefits

  • Integrated high voltage level-shift function
  • Adjustable minimum and maximum frequencies
  • UnderVoltage LockOut (UVLO)
  • Fault latch reset input
  • Wide (max 20 V) supply voltage range
  • Integrated high voltage bootstrap diode
  • Low start-up current (green function)
  • Adjustable non-overlap time
  • Internal OverTemperature Protection (OTP)
  • OverCurrent Protection (OCP) that activates a shut-down timer
  • Soft start timing pin
  • Transconductance error amplifier for ultra high-ohmic regulation feedback
  • Latched shut-down circuit for OverVoltage Protection (OVP)

Applications

  • TV and monitor power supplies
  • High voltage power supplies
