Product Summary

The TEA2261 is a monolithic integrated circuit for the use in primary part of an off-line switching mode power supply. All functions required for SMPS control under normal operating, transient or abnormal conditions are provided. The capability of working according to the “master-slave” concept, or according to the “primary regulation” mode makes the TEA2261 very flexible and easy to use. This is particularly true for TV receivers where the IC provides an attractive and low cost solution (no need of stand-by auxiliary power supply).

Parametrics

TEA2261 absolute maximum ratings: (1)VCC Power Supply V16-V4, 5, 12, 13: 20 V; (2)V+ Output Stage Power Supply V15-V4, 5, 12, 13: 20 V; (3)IOUT+ Positive Output Current (source current): 1.5 A; (4)IOUT- Negative Output Current (sink current): 2.5 A; (5)Tj Operating Junction Temperature: 150℃; (6)Tstg Storage Temperature Range: -40 to +150℃.
