APPLICATIONS

• High current storage inductor for synchronous buck

converter (switch-node interference cancellation)

• High frequency SMPS inductor as storage and EMI filter to

reduce the conducted emissions with grounding of

E-Shield cover

• DC/DC converters for entertainment/navigation systems

• Noise suppression for motors: windshield wipers, power

seats, power mirrors, heating and ventilation blower,

connectivity, audio, and navigation power supply

• LED drivers
