DC-DC converters are widely used in many different industries and applications for converting high voltage DC (direct current) to low voltage DC. The ITQ2415S-H is one such converter from ITQ Corporation that is suitable for many demanding applications, such as telecommunications and industrial control. This converter offers excellent efficiency, high power density, and accurate voltage and current control.

The ITQ2415S-H is a 120 W non-isolated DC-DC converter that provides a wide 4:1 input voltage range and is designed for communications and industrial applications requiring precise output voltage and current control. It offers a high efficiency of 92% with low no-load power consumption. It has an adjustable output voltage range of 0.6 – 3.3 V and a fixed output current range of 0 – 30 A. The ITQ2415S-H is equipped with a digital control interface that enables accurate voltage/current control and monitoring in applications such as telecom power systems and industrial control.

The ITQ2415S-H operates on a basic flyback topology. When the switching device is on, the input voltage is charged to the inductor. When the switch is turned off, the inductor will act as a transformer and delivers the load current. The peak current in the inductor is controlled by the duty cycle, i.e. the larger the duty cycle, the larger the peak current, and due to the strong power relationship, a higher output voltage with a lower duty cycle will be achieved. This makes the output voltage adjustable within the given range by changing the duty cycle.

The ITQ2415S-H has many safety protections, including overvoltage, overcurrent, and short circuit protections. The overvoltage protection will protect the converter if the output voltage rises beyond its specified range. The output current is also monitored and can protect against over-current conditions. There is also an internal temperature sensing device that will shut down the converter in the event of an over temperature condition.

In addition to these features, the ITQ2415S-H offers flexible control functions including remote sensing, over voltage trip, current foldback, and soft-start. Its remote sensing feature can correct for voltage drops that occur between the converter and the load, thus ensuring accuracy even in long runs. The over voltage trip feature ensures that the output is not over voltaged, while the current foldback feature provides improved efficiency. Soft-start will prevent inrush current but also allows for precise output control. The ITQ2415S-H is an extremely versatile device, suitable for many applications where precise power control is needed.

The ITQ2415S-H is an excellent choice for applications where precise voltage and current control is required. It offers a wide input voltage range, a high efficiency, and many safety features. With its adjustable output voltage range, remote sensing, over voltage trip, current foldback, and soft-start features, the ITQ2415S-H is a great DC-DC converter for many communications and industrial applications.
