Safety Considerations:

For safety agency approval of the system in which the DC-DC power module is installed, the power module must be installed in compliance with the creepage and clearance requirements of the safety agency. The isolation is basic insulation. For applications requiring basic insulation, care must be taken to maintain minimum creepage and clearance distances when routing traces near the power module.

As part of the production process, the power modules are hi-pot tested from primary and secondary at a test voltage of 1500Vdc.

To preserve maximum flexibility, the power modules are not internally fused. An external input line normal blow fuse with a maximum value of 10A is required by safety agencies. A lower value fuse can be selected based upon the maximum dc input current and maximum inrush energy of the power module.

When the supply to the DC-DC converter is less than 60Vdc, the power module meets all of the requirements for SELV. If the input voltage is a hazardous voltage that exceeds 60Vdc, the output can be considered SELV only if the following conditions are met:

1)The input source is isolated from the ac mains by reinforced insulation.

2)The input terminal pins are not accessible.

3)One pole of the input and one pole of the output are grounded or both are kept floating.

4)Single fault testing is performed on the end system to ensure that under a single fault, hazardous voltages do not appear at the module output.

iQM Series specifications

The TDK iQM Series represents a significant advancement in the realm of power inductors, catering specifically to applications that demand high efficiency and reliability. Designed for use in a variety of devices, including smartphones, tablets, and power supply systems, the iQM Series is tailored to meet the rigorous demands of modern electronics.

One of the standout features of the iQM Series is its compact size. The inductors are designed to maximize performance while minimizing space, making them ideal for applications where every millimeter counts. This compact design is achieved without compromising on performance, offering high inductance values that are essential for stable operation in power conversion circuits.

TDK has integrated innovative materials in the iQM inductors, utilizing a composite magnetic core that enhances energy efficiency and thermal performance. This ensures that the inductors operate effectively even at higher currents, reducing losses associated with heat generation. As a result, the iQM Series boasts a low DC resistance, contributing to improved overall system efficiency and enabling reliable operation in demanding environments.

Another notable characteristic of the iQM Series is its broad range of inductance values, which allows designers to select the most suitable inductor for their specific application requirements. This adaptability, combined with a wide operating temperature range, enables the iQM inductors to function efficiently in various climatic conditions and across different electronic devices.

Furthermore, the iQM Series is designed with a focus on minimizing noise. Advanced construction techniques have been employed to reduce electromagnetic interference, which is crucial for maintaining signal integrity in high-frequency applications. This makes the iQM Series particularly well-suited for power management circuits used in applications like DC-DC converters and power supply solutions.

The iQM Series also boasts impressive saturation current ratings, allowing for reliable performance even in peak current scenarios. This feature is essential for applications where transient loads can cause inductors to experience higher than normal currents. The ability to handle such conditions without saturating ensures longer device life and better performance under stress.

In summary, the TDK iQM Series of power inductors stands out due to its compact design, high efficiency, versatile inductance values, and effective noise reduction features. These qualities make iQM inductors an excellent choice for engineers looking to enhance their power management circuits in today's technologically advanced devices.
