Switched Mode Power Supply Controller 16-Pin SOIC T/R

The GreenChip is the latest generation of green Switched Mode Power Supply (SMPS) controller ICs. The TEA1755LT 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.

• 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 patented)
• High level of integration, results in cost-effective designs with very low external component counts
• 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
• Valley/Zero-Voltage Switching (ZVS) for minimum switching losses
• Frequency limitation reduces switching losses
• PFC switched off when a low-load is detected at the flyback output Valley switching for minimum switching losses (NXP Semiconductors patented)
• Frequency reduction with adjustable minimum peak current at low-power operation maintains high-efficiency at low output power levels
• Burst mode operation at very low-power levels for high-efficiency operation Valley switching for minimum switching losses (NXP Semiconductors patented)
• Frequency reduction with adjustable minimum peak current at low-power operation maintains high-efficiency at low output power levels
• Burst mode operation at very low-power levels for high-efficiency operation
