STARplugTM
TEA152x family
FEATURES
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.
• Designed for general purpose supplies up to 50 W
• Integrated power switch:
– TEA1520: 48 Ω; 650 V
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.
– TEA1521: 24 Ω; 650 V
– TEA1522: 12 Ω; 650 V
– TEA1523: 6.5 Ω; 650 V
– TEA1524: 3.4 Ω; 650 V.

APPLICATIONS
Typical application areas for the STARplugTM are:
• Temperature protection
• Chargers
• Short circuit winding protection
• Adapters
• Simple application with both primary and secondary
(opto) feedback
• STB (Set Top Box)
• DVD
• Available in 8-pin DIP, 14-pin SO and 9-pin DBS
packages.

• TV/monitor standby supplies
• PC peripherals
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.
• Microcontroller supplies in home applications and small
portable equipment, etc.
