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).
This document is a product specification datasheet for the Philips TEA152x family of Integrated Circuits (ICs). The devices are designed as Switched Mode Power Supply (SMPS) controllers that operate directly from rectified universal mains voltage. They feature an integrated high-voltage power switch and utilize valley switching to minimize switch-on losses, enabling efficient slim-line electronic power plug concepts.
