DC-DC converters are used in a variety of applications that require efficient power conversion from one DC voltage to another. The IW1215SA is one such converter, designed for applications that require high efficiency and high power density. This section will discuss the application field and working principle of the IW1215SA.

Application Field

The IW1215SA is a high-efficiency DC-DC converter which is capable of transforming voltage levels from a low input voltage to a higher output voltage with a high efficiency. It provides a wide range of input and output voltage levels and is capable of achieving up to 90% efficiency. Its small size and high power-to-size ratio make it perfect for power-sensitive applications such as wireless communication equipment, medical equipment, and LED lighting systems.

Working Principle

The IW1215SA operates on a fixed frequency step-down switching converter circuit. This type of converter circuit has an input filter to remove any input ripple, followed by a transformer to reduce the input voltage to the desired level. The output voltage is adjusted by changing the turn ratio of the transformer. This type of converter has a low input voltage drop and is very efficient.

The IW1215SA operates in fixed frequency operation. This means that the switching frequency of the converter remains constant over the full input voltage range and is set by an external component. The output voltage can be set by adjusting the switching frequency. Because of its low power consumption, the IW1215SA can be used in always-on applications such as medical equipment or LED lighting systems.

Conclusion

The IW1215SA is a high-efficiency, high-power density DC-DC converter designed for applications with strict space and power requirements. Its wide range of input and output voltage levels and efficiency make it perfect for power-sensitive applications such as wireless communication equipment, medical equipment, and LED lighting systems. It operates on a fixed frequency step-down switching converter circuit with low input voltage drop which is ideal for always-on applications.
