LM3354MM-3.3/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM3354MM-3.3/NOPB is a fixed-output charge pump switching regulator manufactured by Texas Instruments. It provides a stable 3.3 V output from an input voltage range of 2.5 V to 10 V. The device operates with a typical switching frequency of 1 MHz, enabling the use of small external components. Packaged in a 10-pin VSSOP (MSOP) footprint, it integrates internal switches and control logic for efficient step-up or step-down regulation without requiring inductors.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact suffix 'NOPB' indicates lead-free and RoHS compliance as per Texas Instruments specifications. Confirm the package designation matches the required MSOP-10 footprint for PCB layout compatibility. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and traceability. Check for any recent lifecycle notices or obsolescence warnings directly from the manufacturer before finalizing procurement plans.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when an inductorless solution is preferred to minimize magnetic interference and physical size. It is suitable for applications where moderate efficiency is acceptable in exchange for reduced bill of materials complexity. Ensure the load current requirements fall within the device's specified output current capabilities. Consider thermal performance under maximum load conditions given the compact package size.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to Texas Instruments' LM3354 series of charge pump regulators. These devices are designed for applications needing isolated or non-isolated voltage translation without inductors. The series offers fixed output voltages and is commonly used in portable consumer electronics where space constraints and simplicity are critical design factors.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other LM3354 variants with different output voltages or packages, such as LM3354MM-5.0/NOPB for 5 V output. Verify pin compatibility and electrical characteristics before substitution. Alternative charge pump regulators from other manufacturers may require circuit redesign due to differing control interfaces or pinouts.
