DC DC Switching Controllers Procurement Notes

Verify the exact suffix #PBF indicates lead-free packaging compliant with RoHS standards. Confirm the SOIC-8 package type matches your PCB footprint requirements. Check current availability status as supply may be restricted or subject to factory special orders. Ensure the fixed 3.3 V output aligns with your system design needs before procurement.

DC DC Switching Controllers Selection Notes

Select this component when a compact, high-efficiency solution is required for stepping down higher voltages to 3.3 V. The synchronous design offers superior efficiency compared to non-synchronous alternatives, particularly under light loads. Consider the 700 mA output current limit and the specific input voltage range when designing the power stage. The integrated shutdown pin allows for easy power management integration.

DC DC Switching Controllers Part Context

This part belongs to the LTC1148 series of high-efficiency synchronous buck regulators from Analog Devices.
