Product Summary

The TEA1523 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 TEA1523 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 TEA1523 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. The applications of the TEA1523 include Chargers, Adapters, Set Top Box (STB), DVD, CD(R), TV/monitor standby supplies, PC peripherals, Microcontroller supplies in home applications and small portable equipment, etc.
