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.
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.

APPLICATIONS
Typical application areas for the STARplugTM are:
· Chargers
· Adapters
· STB (Set Top Box)
· DVD
· CD(R)
· TV/monitor standby supplies
· PC peripherals
· Microcontroller supplies in home applications and small
portable equipment, etc.
