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 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: 48 Ω; 650 V

◆ TEA1521x: 24 Ω; 650 V

◆ TEA1522x: 12 Ω; 650 V

◆ TEA1523P: 6.5 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

■ Available in DIP8 and SO14 packages

Applications

■ Chargers

■ Adapters

■ Set-Top Box (STB)

■ DVD

■ CD(R)

■ TV/monitor standby supplies

■ PC peripherals

■ Microcontroller supplies in home applications and small portable equipment, etc.
