TEA1541 is a switch power supply control IC with synchronization function produced by Philips Semiconductors. It has the characteristics of universal power supply, high integration, low power consumption and high reliability.
The TEA1541 is a second-generation GreenChip Switched Mode Power Supply (SMPS) controller IC designed to operate directly from rectified universal mains. It offers a high level of integration, requiring few external components, and features an internal oscillator that can be synchronized to an external signal source. The IC includes proprietary EZ-HV SOI process capabilities for start-up directly from rectified mains voltage.
| Universal mains supply operation | 70 to 276 V AC |
|---|---|
| Standby power consumption (burst mode) | less than 1 W |
| Standby power consumption (low power) | less than 3 W |
| Package type | DIP8 |
| Package name | SOT97-1 |
Yes, its internal oscillator can be synchronized to pulses from an external signal source.
In unsynchronized mode, the frequency decreases to a minimum value of approximately 6 KHz at very low power levels.
