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
