TEA1566 Datasheet PDF

FEATURES

Distinctive features
● High level of integration results in 20 to 50 fewer components compared to a power supply with discrete components
● On-chip 600 V MOSFET
● On/off function replaces expensive mains switch with functional switch
● Direct off-line operation (90 to 276 VAC)
● On-chip 5% accurate oscillator. Green features
● Low power consumption in off-mode (<100 mW)
● On-chip efficient start-up current source giving fast start-up
● Burst mode stand-by (<2 W) for overall improved system efficiency
● Low power operation mode with lower frequency to reduce switching losses. Protection features
● Demagnetization protection
● Cycle by cycle current limitation with programmable current trip level
● Over voltage protection
● Over temperature protection
● Safe-restart mode with reduced power for system fault conditions. Highly versatile
● Usable in Buck and flyback topology
● Interfaces both primary and secondary side feedback.
