High frequency IHLP inductor series boosts DC-DC efficiency

Vishay Intertechnology has introduced the first extended-frequency inductor in the low profile, high current IHLP family. The new IHLP-1616BZ-0H series features high frequency performance up to 10 Hz with the lowest losses of any inductor on the market for frequencies of 1MHz and above. By using the device, designers can improve efficiency and potentially reduce the size of DC-DC converter circuitry. Typical applications for the device will include notebook and desktop computers, sensors, cameras, POL converters, and various battery powered devices that require one or more regulated voltages. Working in conjunction with high frequency controller ICs, the device allows lower inductance values and thus lower DC losses, as well as reduced high frequency core losses, enabling a physically smaller size of inductor to be used while boosting energy efficiency. The series features a typical DCR from 5.5mOhm to 26.6mOhm and inductance values from 0.10µH to 1µH. The device provides rated current to 45A and handles high transient current spikes without saturation. Packaged in a 100% lead (Pb)-free shielded, composite construction that reduces buzz noise to ultra low levels, the inductor offers high resistance to thermal shock, moisture, and mechanical shock. The device is RoHS-compliant, halogen-free, and Vishay Green.
