TEA152x family is a high voltage EZ-HV SOI process, combined with low voltage BICMOS process, implemented switched mode power supply (SMPS) controller IC that operates directly from the rectified universal mains. 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 provides a very efficient switching and allows flexible design by adjusting the frequency.
The TEA152x family is a switched‑mode power‑supply controller IC that operates directly from rectified universal AC mains (80 V to 276 V). It integrates a high‑voltage power switch and supports output powers up to 50 W, making it suitable for compact flyback converters and low‑cost power‑plug solutions.
Key features include adjustable frequency, valley switching (except AJM versions), adjustable over‑current, under‑voltage, temperature and short‑circuit winding protection, and availability in 8‑pin DIP, 14‑pin SO and 9‑pin DBS packages. Typical applications are chargers, adapters, set‑top boxes, DVD/CD players, TV standby supplies, PC peripherals and micro‑controller supplies.
