Online switching loss calculator
for Vishay's inductors
Vishay launched free web-based tool that computes the
switching losses for its IHLP inductors. The simple-to-use
switching loss calculator is customizable to individual
applications, allowing designers to select the correct part
for an optimized board design, while speeding time to market.
The switching loss calculator is available for buck, boost,
and buck/boost dc-to-dc converter topologies.
To compute inductor losses in the past, designers had to
complete the complicated Steinmetz Equation by hand, a time-consuming
process that increases the chances for human error.
With Vishay's loss calculator, available at http://www.vishay.com/inductors/calculator-home-list/,
designers simply enter the input and output voltage, frequency,
output current, and ambient temperature for their application.
With the selection of an inductance value, ranging from
0.1 µH to 10 µH, the calculator immediately
provides results for copper, core, and total losses along
with the estimated temperature rise of the inductor. The
correct Vishay IHLP part number is also displayed for the
The calculator is useful for all IHLP inductor applications,
including voltage regulator module (VRM) and dc-to-dc converter
