TEA1733CP/N1,112 is a low voltage start-up flyback controller suitable for fixed frequency/CCM. It is part of the GreenChip™ series of NXP, which aims to provide energy-efficient solutions for power applications. It uses a proprietary high-voltage BCD800 process that allows direct start-up from the rectified universal mains voltage.
TEA1733CP/N1,112 can be used for various applications that require isolated power conversion, such as:
• AC adapters
• Chargers
• LED drivers
• Auxiliary power supplies
• Industrial power supplies
• Q: How can I design a flyback converter using TEA1733CP/N1,112?
• A: You can use the design tool provided by NXP to design a flyback converter using TEA1733CP/N1,112. The design tool can help you select the optimal components and parameters for your application, and generate a schematic, a bill of materials, and a performance report.
• Q: What are the advantages of TEA1733CP/N1,112 over other flyback controllers?
• A: TEA1733CP/N1,112 has several advantages over other flyback controllers, such as:
• Low start-up current of 10 µA, which reduces the power consumption in standby mode
• High level of integration, which reduces the external component count and cost
• High switching frequency of 66.5 kHz, which allows the use of smaller and cheaper transformers and capacitors
• Advanced protection features, such as overcurrent, overvoltage, overtemperature, and over power, which enhance the reliability and safety of the converter
• GreenChip™ technology, which meets the stringent energy efficiency standards and regulations
