Protection Circuit Design Of A Single Energy-saving Lamp Driver Chip

With the continuous rapid economic development, people now pay more attention to energy conservation, with the "green light" applications, especially the requirement to replace the traditional incandescent lamp with a variety of energy-saving lamps. In this paper, the design of its protection circuit for a single energy saving lamp driver chip, can be adapted to a stable, high efficiency, low heat dissipation at 220 V AC civilian work environment. Specialized device integrated module of the chip can be good for each device isolation, and try to reduce the size of the chip design, work processes and short response time. The driver chip protection circuits are mainly discussed on the pulse trigger circuit, short-circuit protection fault timer peripheral resistance temperature detector, abnormal signal generating circuit, compared with the current sampling circuit, ESD anti-static protection for the entire chip function modules to achieve effective protection.In this paper, each unit circuit of the protection circuit is schematics designed, and completed the simulation experimental testing. By comparing with the design parameters, experimental results of the circuit can reach the expectation and run at low power, high efficiency under conditions to ensure reliability. Effectively control the size of the chip, shorten response time.The design of the protection circuit can be used to power devices with LED energy saving lamp driver chip, from the design characterization, can also be used for other low-power energy-saving lighting products, its wide application surface. Implementation and testing simulation designed to protect part of the circuit. Disadvantages specialized device integrated module of the chip, and can be a good electromagnetic, optical isolators, decreases, and try to reduce the size of the chip design, work processes and short response time.Based on the integration requirements, this design enables a better chip packages and packaging materials in order to achieve low power conditions to achieve reliability, thermal effects, and lower costs. Each part of the circuit of the drive circuit, in the experimental simulation environment to build applications work platform, using the experimental test instruments designed to collect and complete comparison of the various parameters. By analyzing the test results, you can achieve the required functionality and working standards of the design of the chip, the chip work to ensure heat dissipation, stability, good efficiency, and suitable for the production of products used in energy-saving lamps. Analysis the semiconductor materials selection, and introduces electrostatic protection technology in large-scale production environment of ESD protection circuit. Design a suitable energy-saving light-emitting diode lamp power driver IC. Refer to the design and function of the various components, which are focusing on the completion of the circuit to achieve protection. Also complete the driver circuit chip layout design based on this platform on.
