General description
The TEA152x family STARplug is a Switched Mode Power Supply (SMPS) controller IC that operates directly from the rectified universal mains. It isimplemented 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.

Features and benefits
„ Designed for general purpose supplies up to 30 W
„ Integrated power switch:
   ‹TEA1520x: 48Ω; 650 V
   ‹TEA1521x: 24Ω; 650 V
   ‹TEA1522x: 12Ω; 650 V
   ‹TEA1523P: 6.5Ω; 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

 Applications
„ Chargers
„ Adapters
