TEA2260 TEA2261 SWITCH MODE POWER SUPPLY CONTROLLER . . . . . . . . . . POSITIVE AND NEGATIVE CURRENT UP TO 1.2A and – 2A LOW START-UP CURRENT DIRECT DRIVE OF THE POWER TRANSISTOR TWO LEVELS TRANSISTOR CURRENT LIMITATION DOUBLE PULSE SUPPRESSION SOFT-STARTING UNDER AND OVERVOLTAGE LOCK-OUT AUTOMATIC STAND-BY MODE RECOGNITION LARGE POWER RANGE CAPABILITY IN STAND-BY (Burst mode) 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 "masterslave" 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.
