• Operates with a fixed switching frequency of 120 kHz

Applications

• General LED lighting systems
• Buck converter topologies for LED drivers
• Single-output LED illumination modules

Procurement Notes

Verify the exact part number suffix against official Infineon documentation to confirm package type and tape/reel specifications. Ensure compatibility with existing PCB footprints for the SC-74-3D package. Confirm that the 120 kHz switching frequency aligns with system EMI requirements and inductor selection criteria before procurement.

Selection Notes

Select this component when a single-channel buck LED driver with integrated switching capability is required. The 350 mA output current rating suits standard LED strings. Consider the 120 kHz frequency for balancing efficiency and passive component size. Verify input voltage ranges against specific application needs using the official datasheet.

Part Context

This part belongs to Infineon's LED driver portfolio, specifically designed for DC-DC step-down applications. It simplifies design by integrating the power switch, reducing external component count compared to discrete solutions. The SC-74-3D package offers space-efficient mounting for modern electronic devices.

Replacement Considerations

Consult official Infineon substitution guides for verified alternatives. Generic equivalents may differ in integrated switch characteristics or switching frequency.
