Working Principle of LM3S1N11-IQC50-C5T

The LM3S1N11-IQC50-C5T is a quasi-resonant converter that operates by switching the input power at a frequency of 50 kHz in order to achieve high efficiency and stable output. The input voltage is applied to both the primary inductor and the switching transistors. The current in the inductor is then changed to the desired output voltage level. The switch transistors are periodically turned on and off so that the current in the inductor is controlled and remains constant. The output voltage is then regulated by controlling the time the switches are on and off.This converter can achieve high efficiency due to its quasi-resonant operation, which reduces the switching losses of the converter. The LM3S1N11-IQC50-C5T has a wide range of operating voltage inputs, from 85V to 296V, and can support a steady-state output current of up to 2.5A.In addition to its high efficiency, the LM3S1N11-IQC50-C5T also has a low profile, which makes it suitable for applications requiring a compact design. The converter is available in a 8x8x2 mm package, making it ideal for applications with space constraints. Other features of the LM3S1N11-IQC50-C5T include a start-up time of less than 2ms, a maximum operating temperature of -30°C to 95°C, and a working frequency of 50kHz.
