OR:  

The TEA1723 is a small and low cost module Switched Mode Power Supply (SMPS) controller IC for low power applications (up to 11 W) and operates directly from the rectified universal mains input. The device includes a high voltage power switch (700 V) and has been optimized for flyback converter topologies to provide high-efficiency over the entire load range with ultra-low power consumption in the no-load condition. It provides a circuit for start-up directly from the rectified mains voltage without any external bleeder circuits. The Burst mode frequency of 1850 Hz enables no-load power consumption below < 53 mW at high mains input.

Features and benefits

  • Low power SMPS controller for applications up to 11 W
  • 700 V high voltage power switch for global mains operation
  • Primary sensing without optocoupler and secondary feedback circuitry
  • Minimizes audible noise in all operation modes
  • Energy Star 2.0 compliant
  • Jitter function for reduced EMI
  • Enables no-load power consumption < 53 mW
  • Very low supply current in no-load condition with energy saver mode
  • High voltage start-up circuit with zero current consumption during switching
  • Available in halogen-free and (RoHS) SO7 package
  • OverVoltage Protection (OVP) on supply pin and on (FB) pin with auto-restart
  • UnderVoltage LockOut (UVLO) protection on IC supply pin
  • OverTemperature Protection (OTP)
  • Soft-start by reduced peak current for zero and low output voltage
  • Demagnetization protection for guaranteed discontinuous conduction mode
  • Open and short-circuit protection of the Feedback control (FB) pin

Applications

  • White goods
  • Industrial
  • Smart meters
  • Chargers for smartphones and media tablets
  • General-purpose adapters
