FEATURES
● Designed for general purpose supplies up to 50 W● Integrated power switch: – TEA1520: 48 Ω; 650 V – TEA1521: 24 Ω; 650 V – TEA1522: 12 Ω; 650 V – TEA1523: 6.5 Ω; 650 V – TEA1524: 3.4 Ω; 650 V.
● Operates from universal AC mains supplies (80 to 276 V)
● Adjustable frequency for flexible design
● RC oscillator for load insensitive regulation loop constant
● Valley switching for minimum switch-on loss (not implemented in TEA152xAJM versions)
● Frequency reduction at low power output makes low standby power possible (<100 mW)
● Adjustable overcurrent protection
● Under voltage protection
● Temperature protection
● Short circuit winding protection
● Simple application with both primary and secondary (opto) feedback
● Available in 8-pin DIP, 14-pin SO and 9-pin DBS packages.
GENERAL DESCRIPTION
The TEA152x family 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 BICMOS process.
