Circuito Integrado Switched Mode Power

Designed for general purpose supplies up to 50 W
Integrated power switch:
– TEA1520: 48; 650 V
– TEA1521: 24; 650 V
– TEA1522: 12; 650 V
– TEA1523: 6.5; 650 V
– TEA1524: 3.4; 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.
