仕様・特性

TEA2261/0 SWITCH MODE POWER SUPPLY CONTROLLER Positive and Negative Current up to 1.2A and 2A s Low Start-Up Current s Direct Drive of the Power Transistor s Two Levels Transistor Current Limitation s Double Pulse Suppression s Soft-Starting s Under and Overvoltage Lock-out s Automatic Stand-By Mode Recognition s Large Power Range Capability in Stand-By (Burst Mode) s Internal PWM Signal Generator DESCRIPTION The TEA2260/61 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 TEA2260/61 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). See application note AN376/ 0490 for detailed information. s (s) ct uc d te le so Ob - s) t( ro P BATWING DIP16 (Plastic Package) ORDER CODES: TEA2261/0 du o Pr e Figure 1.
