General description

The TEA1620P 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, which makes a

very efficient slim-line electronic power-plug concept possible.

In its most basic version of application, the TEA1620P 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

TEA1620P renders an efficient and low cost power supply system.
