TEA1521T
Overview
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.
- 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
