• Operates from universal AC mains supplies (80 to 276 V) • Adjustable frequency for flexible design • RC oscillator for load insensitive regulation loop constant • Valley switching for minimum switch-on loss (not implemented in TEA152xAJM versions) • Frequency reduction at low power output makes low standby power possible (<100 mW) • Adjustable overcurrent protection • Under voltage protection • Temperature protection • Short circuit winding protection • Simple application with both primary and secondary (opto) feedback • Available in 8-pin DIP, 14-pin SO and 9-pin DBS packages.
GENERAL DESCRIPTION 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.
APPLICATIONS TEA152x family A dedicated circuit for valley switching is built in (not implemented in TEA152xAJM versions), which makes a very efficient slim-line electronic powerplug concept possible.
In its most basic version of application, the TEA152x family 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 TEA152x family renders an efficient and low cost power supply system.
