LM3354MM-3.7/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM3354MM-3.7/NOPB is a charge pump switching regulator IC manufactured by Texas Instruments, housed in a 10-VSSOP package. It provides a fixed positive output voltage of 3.7V with a maximum output current of 90mA. The device operates from an input voltage range up to a maximum of 5.5V and utilizes a synchronous rectifier topology for improved efficiency. The internal switching frequency is fixed at 1MHz, allowing for the use of small external components. This component belongs to the LM3354 base product family.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free and RoHS compliance status as per manufacturer documentation. Ensure the 10-VSSOP package dimensions match your PCB footprint requirements. Confirm that the fixed 3.7V output aligns with your load specifications, as alternative variants such as the LM3354MM-1.8/NOPB exist within the same family. Cross-reference the official Texas Instruments datasheet for thermal performance data under expected operating conditions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.7V output is required from an input voltage up to 5.5V. The 1MHz switching frequency supports compact designs but requires attention to electromagnetic interference. Consider the 90mA output current limit against peak load demands. Compare with other LM3354 variants if different output voltages like 1.8V or 4.1V are needed instead.

Voltage Regulators - DC DC Switching Regulators Part Context

This part is a variant of the LM3354 series, which includes models with different fixed output voltages such as LM3354MM-1.8/NOPB and LM3354MM-4.1/NOPB. All share the same synchronous charge pump topology and 10-VSSOP package. The LM3354 family is designed for space-constrained applications requiring efficient voltage conversion from single-cell sources.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other LM3354 variants with matching package and functionality, such as LM3354MM-1.8/NOPB or LM3354MM-4.1/NOPB, provided the output voltage difference is acceptable. Verify pin compatibility and thermal characteristics before substitution.
