Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the complete part number including the NOPB suffix to confirm lead-free compliance and specific package variant. Confirm the 520 kHz switching frequency requirement matches your design constraints, as other variants may offer different frequencies. Ensure the SOT-23-5 footprint aligns with your PCB layout specifications before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 520 kHz frequency is required for EMI filtering compatibility. It is suitable for applications needing up to 2.1 A output current from a single-cell lithium battery source. Consider alternative LM2735 variants if a higher 1.6 MHz frequency or automotive AEC-Q100 qualification is necessary for the specific application environment.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM2735 family of space-efficient boost regulators. It shares architectural similarities with other members like the LM2735XQMFX/NOPB but differs in switching frequency and qualification standards. The YMFX/NOPB designation specifically identifies the non-automotive grade version with the 520 kHz fixed frequency option in the SOT-23-5 package.
