Procurement Notes

Verify the specific suffix 'BETR' corresponds to the tape and reel packaging format when ordering. Confirm that the 8-pin SOIC EP wide package meets your PCB layout requirements. Ensure the 64 kHz switching frequency aligns with your electromagnetic interference constraints. Check that the 0.9 A output current capability satisfies the target LED string design. Validate the -40°C to +85°C operating temperature range against environmental conditions.

Selection Notes

Select this component for applications requiring a cost-effective, high-voltage LED driver compatible with both AC mains and wide-range DC inputs. The integrated buck topology simplifies circuit design for step-down voltage conversion. Consider the 64 kHz operating frequency for balancing efficiency and component size. The SOIC EP package offers thermal dissipation benefits for compact designs. Verify compatibility with PWM dimming signals if variable brightness control is required.
