TEA152x
SMPS ICs for low-power systems
Rev. 04 — 14 September 2010
Product data sheet
1. General description
The TEA152x family STARplug 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 Bipolar Complementary
Metal-Oxide Semiconductor (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, which makes a very efficient slim-line
electronic power-plug 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.
2. Features and benefits
