TEA1521T 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, bined with a low-voltage Bipolar plementary 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.
TEA1521T Key Features
- Designed for general purpose supplies up to 30 W
- Integrated power switch
- 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
