LM2682MX/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2682MX/NOPB is a switched capacitor voltage converter manufactured by Texas Instruments, designed to generate negative output voltages from positive input sources. It operates within an input voltage range of 2 V to 5.5 V and provides a maximum output current of 10 mA. The device functions as an inverting charge pump with a typical switching frequency of 15 kHz. It is housed in an 8-pin SOIC package (SOIC-8) and supports an operating temperature range from -40 °C to +85 °C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Generates negative output voltages using switched capacitor topology
• Operates efficiently at low switching frequencies for reduced noise
• Provides fixed negative output configurations relative to input

Voltage Regulators - DC DC Switching Regulators Applications

• Biasing operational amplifiers requiring dual power supplies

• Powering RS-232 interface components in single-supply systems

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'MX' corresponds to the SOIC-8 package variant when sourcing. Confirm RoHS compliance status via the manufacturer's official documentation, as 'NOPB' typically indicates lead-free and halogen-free construction. Ensure the supplier provides valid traceability data for quality assurance purposes.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution is needed for generating moderate negative currents from a single positive supply. Consider the 10 mA output limit and 15 kHz switching frequency against system noise requirements. Evaluate thermal performance within the specified -40 °C to +85 °C ambient range for the target application environment.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2682 family of switched capacitor converters. It shares functional similarities with other TI charge pump devices but is distinct in its specific pinout, package type, and electrical characteristics tailored for general-purpose inverting applications.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Consult official substitution guides for compatible alternatives such as the LM2682MM/NOPB or LM2682M/NOPB, which offer similar functionality in different packages like VSSOP or standard SOIC.
