Coiltronics ? High Frequency Inductor Catalog
High Frequency Inductors for Core Power Applications
The trend in modern power conversion is for high power density, reduced
volume and increased efficiency. The drive for smaller, more efficient
solutions presents a number of challenges for circuit design and component
selection.
Inductor selection in high current core power applications is based on a need
for high peak current ratings and low high frequency losses. These two
requirements lead designers in different directions resulting in a compromise
solution. Designers are forced to select low inductance values to reduce
inductor size (and ensure fast transient responses which results in high
ripple currents needing to be absorbed by the inductor increasing losses) or
select higher inductance values to reduce the ripple current and losses - but
at a sacrifice of inductor size, efficiency and transient responses.
The material of choice for core power multi-phase uncoupled inductors is
ferrite. Core power applications require a high saturation, high frequency, low
loss, wide temperature range ferrite material to be selected. The reduced
core loss at high frequency (coupled with a very low Direct Current
Resistance - DCR - single turn rectangular conductor) ensures high
efficiency (see Figure 1).

Current Sensing
When accurate current sensing is required, a low value resistor is commonly
used to generate a voltage proportional to the output current. The introduction
of such a current sense resistor increases the circuit losses along with overall
converter size and cost. Using an output inductor with a tight DCR tolerance
will eliminate the need for the current sense resistor.

Figure 2 shows a typical inductor current sense circuit, where the voltage
across Cs is equal to the volt drop across the inductor DCR when the RC time
constant is equal to the inductor time constant (R*C=L/RI). The low DC
resistance at tight tolerance enables the inductor to also function as a current

Comparing the performance of traditional ferrite inductors (such as the FP2
with the new DCR current sense inductors from Cooper Bussmann) it can be
seen that the benefits go beyond the elimination of sensing resistors.
