Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'LD' indicates the 16-WSON package variant distinct from standard SOIC or DIP versions. Confirm the '-12' designation corresponds to the fixed 12V output option. Ensure 'NOPB' confirms lead-free and RoHS compliance status. Cross-reference the manufacturer datasheet for exact pinout and thermal pad requirements to prevent installation errors during procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12V output is required from an input source between 8V and 40V. It is appropriate for designs needing 500mA continuous load current with high efficiency. The choice depends on the availability of the 16-WSON package for surface-mount assembly. Consider thermal management needs due to the small package size and power dissipation characteristics at higher load currents.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2674 SIMPLE SWITCHER family, which offers integrated buck converters. The LD suffix specifically denotes the 16-WSON package, differentiating it from other variants like the MX (SOIC) or N (DIP). This family is characterized by high efficiency and simplified design implementation through integrated power switches and control logic.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other LM2674 variants with matching electrical specifications but different packages, such as LM2674MX-12/NOPB or LM2674N-12/NOPB. Verify pin compatibility and thermal performance if changing package types. Adjacent models like LM2675 may offer higher current capacity but require circuit adjustments.
