TEA1755LT Overview
The GreenChip is the latest generation of green Switched Mode Power Supply (SMPS) controller ICs. The TEA1755LT bines 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 ponents.
TEA1755LT Key Features
- Integrated PFC and flyback controller
- Universal mains supply operation between 70 V (AC) to 276 V (AC)
- Dual-boost PFC with accurate maximum output voltage (NXP Semiconductors
- High level of integration, results in cost-effective designs with very low external
- Adjustable PFC switch off delay
- External PFC switch on and switch off override
- Accurate PFC switch on and switch off control (NXP Semiconductors patent pending)
- 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
