TEA1755T/1,518 is the latest generation of green Switched Mode Power Supply (SMPS) controller IC. The TEA1755T combines a controller for Power Factor Correction (PFC) and a flyback controller. Its high level of integration enables cost-effective power supply design using a very low number of external components. The PFC operates in Quasi-Resonant (QR) or Discontinuous Conduction Mode (DCM), with valley switching. The specially built-in green functions provide high efficiency at all power levels. The advanced burst mode ensures high-efficiency at low power and good standby power performance while minimizing audible transformer noise. The device can be used in all applications requiring an efficient and cost-effective power supply solution for up to 250 W. Notebook adapters in particular benefit from the high level of integration.
- Universal mains supply operation between 70V (AC) to 276V (AC)
- Dual-boost PFC with accurate maximum output voltage
- Adjustable PFC switch off delay
- External PFC switch on and switch off override, accurate PFC switch on and switch off control
- On-chip start-up current source
- Reduced IC supply current during burst mode enabling ErP lot 6
- Power-down functionality for very low standby power
- Valley/Zero-Voltage Switching (ZVS) for minimum switching losses
- Hz limitation reduces switching losses, PFC switched off when a low-load is detected at flyback o/p
- Available in 16 pin SO package
