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 Bipolar Complementary Metal-Oxide Semiconductor (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

Features and benefits

  • Designed for general purpose supplies up to 30 W
  • Integrated power switch: 48 Ω; 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

Applications

  • Chargers
  • Adapters
  • Set Top Box (STB)
  • DVD
  • CD(R)
  • TV and monitor standby supplies
  • PC peripherals
  • Microcontroller supplies in home applications and small portable equipment, etc.
