LM2623MM/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2623MM/NOPB is a general-purpose, gated-oscillator-based DC/DC boost converter manufactured by Texas Instruments (formerly National Semiconductor). It operates with an input voltage range of 2.5 V to 18 V and provides a regulated output voltage adjustable from 5 V to 30 V. The device supports a maximum output current of 500 mA and features a fixed switching frequency of 500 kHz. It is housed in a compact 10-pin MSOP package and includes internal compensation for stable operation.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer origin, as National Semiconductor assets are managed by Texas Instruments. Confirm the presence of the NOPB suffix indicates lead-free compliance. Ensure the MM package variant matches the required footprint. Cross-reference the datasheet revision to confirm electrical characteristics align with design specifications before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a simple, cost-effective boost solution is needed for inputs up to 18 V. The 500 mA current limit suits moderate power applications. Consider the MSOP package size for space-constrained designs. Verify that the 500 kHz switching frequency does not interfere with sensitive analog circuits in the system.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2623 family of boost converters. It shares functional similarities with other National Semiconductor/TI switching regulators but is distinct in its gated-oscillator topology. The family targets general-purpose applications where simplicity and low component count are prioritized over high efficiency or complex control features.
