General description

The TEA152x family STARplug 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-HV 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 TEA152x family 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 TEA152x family renders an efficient and low cost power supply system.

Features

  • Designed for general purpose supplies up to 30 W
  • Integrated power switch:
    • TEA1520x: 48 Ohm; 650 V
    • TEA1521x: 24 Ohm; 650 V
    • TEA1522x: 12 Ohm; 650 V
    • TEA1523P: 6.5 Ohm; 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 makes low standby power possible (< 100 mW)
  • Adjustable overcurrent protection
  • Undervoltage protection
  • Temperature protection
  • Short-circuit winding protection
  • Simple application with both primary and secondary (opto) feedback
  • Available in DIP8 and SO14 packages
