TEA1541

The TEA1541 is a second generation GreenChip^TM(1) Switched Mode Power Supply (SMPS) controller IC that operates directly from the rectified universal mains.A high-level of integration provides a cost-effective power supply requiring only a few external components.The TEA1541 controller enables easy design of highly efficient, reliable switched mode power supplies.Its internal oscillator can be synchronized to pulses from an external signal source. External synchronizing pulses whose frequency is above the SMPS switching frequency range are divided by an internal divider.Special built-in green functions ensure optimum efficiency at all power levels.

At low power (standby) levels, the SMPS supply operates at a lower frequency. In burst standby mode, power consumption can be reduced to less than 1 W. The proprietary EZ-HV SOI process allows start-up directly from the rectified mains voltage, avoiding the need for bleeder circuits, and also saves energy.A low voltage BICMOS implements accurate control and high speed protection functions.
