LM3350MM/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM3350MM/NOPB is a charge pump switching regulator IC manufactured by Texas Instruments. It provides positive fixed output voltages derived from the input supply, specifically offering outputs at 3/2Vin and 2/3Vin ratios. The device supports a maximum output current of 50mA and operates within an 8-pin TSSOP or MSOP package with a width of 3.00mm. It is designed for applications requiring efficient voltage conversion without inductors.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Charge pump topology eliminates the need for external inductors
• Fixed voltage conversion ratios of 1.5x and 0.67x relative to input
• Compact surface-mount packaging suitable for space-constrained designs

Voltage Regulators - DC DC Switching Regulators Applications

• Portable battery-powered devices requiring voltage level shifting
• LCD bias voltage generation
• General-purpose DC-DC conversion in compact electronics

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix (NOPB) indicates lead-free/RoHS compliance as per Texas Instruments standards. Confirm the package variant matches the required footprint (TSSOP vs MSOP) as both are referenced in distributor data. Ensure the order quantity aligns with standard reel or cut-tape availability from authorized distributors.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when inductor-free voltage conversion is required for low-current applications up to 50mA. It is suitable for systems needing step-up or step-down functionality from a single supply rail. Consider the fixed ratio constraints; if variable output is needed, a different regulator topology should be evaluated.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM3350 family of charge pump regulators. It serves as a compact alternative to inductive converters for moderate power requirements. The NOPB suffix denotes environmental compliance, distinguishing it from older non-compliant variants within the same functional family.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM3350MMX/NOPB is the tape-and-reel version of the same device. Verify pinout compatibility if substituting with other charge pump ICs from different manufacturers.
