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.
APPLICATIONS
TEA152x family
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.
