TEA1504 Description
plastic dual in-line package; 14 leads (300 mil) GENERAL DESCRIPTION TEA1504 The GreenChip™ TEA1504 is intended for off-line 90 to 276 V (AC) power supply applications. It is one of a family of high voltage ICs integrating both analog and digital circuit functions for controlling a switched mode power supply (SMPS).
TEA1504 Key Features
- High level of integration reduces the number of ponents by up to 50 pared to power supply using discrete ponents
- On/off functional switch replaces expensive mains switch
- Direct off-line operation (90 to 276 V AC)
- 5% accurate on-chip oscillator. Green features
- Low power consumption in off-mode (<100 mW)
- Fast and efficient on-chip start-up current source
- Burst mode standby (<2 W) for overall improved system efficiency
- Low power operation mode with lower frequency reduces switching losses
- Low Overcurrent Protection (OCP) level. Protection features
- Demagnetization protection
