General description

The TEA1620P is a Switched Mode Power Supply (SMPS) controller IC that operates directly from the rectified universal mains. It is implemented in the high voltage EZ-HVTM SOI process, combined with a low voltage BICMOS process.

The device includes a high voltage power switch and a circuit for start-up directly from the rectified mains voltage. A dedicated circuit for valley switching is built in, which makes a very efficient slim-line electronic power-plug concept possible.

In its most basic version of application, the TEA1620P acts as a voltage source. Here, no additional secondary electronics are required. A combined voltage and current source can be realized with minimum costs for external components. Implementation of the TEA1620P renders an efficient and low cost power supply system.

Features

  • Designed for general purpose supplies
  • Integrated power switch: 48 Ohm and 650 V
  • Operates from universal AC mains supplies: 80 V to 276 V
  • Adjustable frequency for flexible design
  • RC oscillator for load insensitive regulation loop constant
  • Valley switching for minimum switch-on loss
  • Frequency reduction at low power output for low standby power: <100 mW
  • Adjustable overcurrent protection
  • Undervoltage protection
  • Temperature protection
  • Short winding protection
  • Safe restart mode for system fault conditions
  • Simple application with both primary and secondary (opto) feedback
  • Available in 8-pin DIP package.
