The input reflected ripple is measured with a current probe and oscilloscope. The ripple current is the current through a 12H differential mode inductor, Lin, with esr 10 m, feeding a capacitor, C1, esr 700 m@ 100kHz, across the module input voltage pins. The capacitor C1 across the input shall be at least 100F/100V. A 220F/100V capacitor is recommended. A 220F/100V capacitor for C0 is also recommended.

The output ripple measurement is made approximately 7 cm (2.75 in.) from the power module using an oscilloscope and BNC socket. The capacitor Cext is located about 5 cm (2 in.) from the power module; its value varies from code to code and is found on the electrical data page for the power module of interest under the ripple & noise voltage specification in the Notes & Conditions column.

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. With TDK's commitment to innovation and quality, the iQM Series is set to play a vital role in the future of electronics.
