Introduction of new technology advantages
Currently, successfully solved the LED market
Many challenges, including integrating more functions into smaller and smaller integrated circuit boards, designing more powerful solutions without increasing costs, and continuing to be at the forefront of consumer trends and customer demand for market-oriented Be the first to introduce a high performance, cost effective solution.
The MIC3205 is an excellent example of a hysteresis, buck, high-brightness LED driver developed by Micrel, and its FM solution is patent-pending to maintain a constant operating frequency over the entire input voltage range. The MIC3205 provides an ideal solution for internal/external lighting, architectural and ambient lighting, LED bulbs and other general lighting applications.
The MIC3205's input voltage ranges from 4.5V to 40V, making it ideal for lighting applications that require a large input voltage range. Hysteresis control ensures good power supply rejection and fast response during load transients and pulse width modulation attenuation. High-side current sensing and on-chip current sense amplifiers provide LED current accuracy of ±5%. This product uses an external high-side current sense resistor to set the output current.
