TEA1566S

INTEGRATED CIRCUITS DATA SHEET TEA1566 GreenChip™; SMPS module Preliminary specification File under Integrated Circuits, IC11 1999 Apr 20 Philips Semiconductors Preliminary specification GreenChip™; SMPS module 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.
