General description
The TEA1733T is a low cost Switched Mode Power Supply (SMPS) controller IC intended for flyback topologies. It operates in fixed frequency mode. To reduce ElectroMagnetic Interference (EMI), frequency jitter has been implemented. Slope compensation is integrated for Continuous Conduction Mode (CCM) operation.

FEATUREs
  SMPS controller IC enabling low-cost applications
  Large input voltage range (12 V to 30 V)
  Very low supply current during start-up and restart (typically 10 A)
  Low supply current during normal operation (typically 0.5 mA without load)
  Overpower or high/low line compensation
  Adjustable overpower time-out
  Adjustable overpower restart timer
  Fixed switching frequency with frequency jitter to reduce EMI
  Frequency reduction with fixed minimum peak current to maintain high-efficiency at low output power levels
  Slope compensation for CCM operation
  Low and adjustable OverCurrent Protection (OCP) trip level
  Adjustable soft start operation
  Two protection inputs (e.g. for input UVP and OVP, OTP and output OVP)
  IC overtemperature protection

APPLICATIONs
  All applications requiring efficient and cost-effective power supply solutions up to 75 W.
