LM2703MF-ADJ/NOPB

Overview

The LM2703MF-ADJ/NOPB is a micropower step-up DC/DC converter manufactured by Texas Instruments. It features an adjustable output voltage configuration with a peak current limit of 350 mA. The device operates within an input voltage range of 2.2 V to 7 V and supports a switching frequency that allows for compact external component sizing. Packaged in a SOT-23-5 surface-mount case, it is designed for battery-powered applications requiring efficient voltage boosting.

Feature Summary

• Micropower step-up DC/DC converter topology
• Integrated 350 mA peak current limit
• Adjustable output voltage capability
• SOT-23-5 surface-mount package

Applications

• Battery-powered portable devices
• Single-cell or multi-cell battery voltage boosting
• Low-power LED driver circuits
• General-purpose step-up power supplies

Procurement Notes

Verify the complete part number including the suffix /NOPB to ensure lead-free compliance and specific tape-and-reel packaging options. Confirm the manufacturer is Texas Instruments to avoid counterfeit components. Check datasheet revisions for any updates to electrical characteristics or recommended operating conditions before finalizing procurement specifications.

Selection Notes

Select this component when a low-cost, small-footstep boost converter is required for currents up to 350 mA. It is suitable for designs where input voltages range from 2.2 V to 7 V. Consider the SOT-23-5 package constraints for thermal management and PCB space. Ensure the application does not exceed the peak current limit for reliable operation.

Part Context

This device belongs to the LM2703 family of micropower converters. It shares functional similarities with the LM2704 but offers lower current capacity. The LM2703 series is designed for cost-sensitive applications requiring simple external feedback networks for voltage adjustment. It serves as a basic building block for portable electronics power management.

Replacement Considerations

Direct substitutes include LM2703MF-ADJ without the NOPB suffix for non-lead-free requirements. Other compatible parts in the same family include LM2704 variants for higher current needs. Verify pin compatibility and electrical parameters before swapping with other boost converters.
