TEA1566S Description
The GreenChip™, intended for off-line 90 to 276 VAC power supply applications, is a monolithic high voltage family of ICs that bines analog and digital circuits to implement all necessary control functions for a switched mode power supply. The functions include integrated high voltage start-up current source, voltage mode PWM control, 5% accurate trimmed oscillator, band gap derived reference voltages, prehensive...
TEA1566S Key Features
- High level of integration results in 20 to 50 fewer ponents pared to a power supply with discrete ponents
- 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
