The TEA1622P 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 TEA1622P 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 TEA1622P renders an efficient and low cost power supply system.
The Philips TEA1622P is a Switched Mode Power Supply (SMPS) controller IC designed for general purpose supplies. It operates directly from the rectified universal mains and is implemented in a high voltage EZ-HV SOI process combined with a low voltage BICMOS process. The device includes an integrated high voltage power switch and a dedicated circuit for valley switching to ensure efficiency in slim-line electronic power-plug concepts.
Key features include operation from universal AC mains supplies (80 V to 276 V), adjustable frequency, and various protection mechanisms such as overcurrent, undervoltage, temperature, and short winding protection. The IC is available in an 8-pin DIP package and supports both primary and secondary feedback applications.
