TEA1751LT Description
The TEA1751LT is the third generation of green Switched Mode Power Supply (SMPS) controller ICs. The TEA1751LT bines a controller for Power Factor Correction (PFC) and a flyback controller. Its high level of integration allows the design of a cost-effective power supply with a very low number of external ponents.
TEA1751LT Key Features
- Integrated PFC and flyback controller
- Universal mains supply operation (70 V (AC) to 276 V (AC))
- Dual-boost PFC with accurate maximum output voltage (NXP patented)
- High level of integration, resulting in a very low external ponent count and a
- On-chip start-up current source
- Valley/Zero Voltage Switching (ZVS) for minimum switching losses (NXP patented)
- Frequency limitation to reduce switching losses
- PFC is switched off when a low load is detected at the flyback output
- Valley switching for minimum switching losses (NXP patented)
- Safe restart mode for system fault conditions
