FEATURES
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. The device includes a high voltage
power switch and a circuit for start-up directly from the
rectified mains voltage.

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.

A dedicated circuit for valley switching is built in (not
implemented in TEA152xAJM versions), which makes a
very efficient slim-line electronic powerplug concept
possible.
In its most basic version of application, the TEA152x family
acts as a voltage source. Here, no additional secondary
electronics are required. A combined voltage and current
source can be realized with minimum costs for external
components. Implementation of the TEA152x family
renders an efficient and low cost power supply system.
