Highly Customizable IPLA 32 Targets Automotive and Embedded High Current, High Power Density DC/DC Converters

MALVERN, Pa. — A new high-current planar choke inductor that offers the same performance as wirewound devices in a fraction of the space was announced today by Vishay Intertechnology, Inc.. The new IPLA 32 measures just 31 mm by 43 mm by 22.2 mm but is rated for currents up to 110 A, allowing high power density DC/DC converters to occupy a significantly smaller footprint.

With a recommended frequency range of 100 kHz to 800 kHz, the IPLA 32 will enable more compact and lightweight DC/DC circuitry in electric and hybrid cars, off-road vehicles including forklifts, and all manner of embedded systems. The IPLA 32 is available with standard inductance values of 1 μH, 2 μH, 3 μH, and 4 μH. Magnetically shielded for low EMI, the inductor features a high self-resonance frequency and very stable performance versus temperature.

In addition to the standard versions, the IPLA 32 can be offered with various pin-out designs, current ratings, and inductance values. The device features an operating temperature range of 55 °C to +125 °C and typical thermal resistance from 2 W/°C to 10.5 W/°C depending on the type of heatsink used. 3D models are available to assist the design-in process.
