LM2682MMX

Voltage Regulators - DC DC Switching Regulators Overview

The LM2682MMX/NOPB is a switched capacitor voltage doubler and inverting charge pump from Texas Instruments, housed in an 8-VSSOP package. It operates with an input voltage range of 2 V to 5.5 V and delivers a fixed output current of 10 mA. The device supports Boost, Buck, and Inverting topologies, providing outputs of -Vin or 2Vin. It functions at a switching frequency of 6 kHz and maintains operation within a temperature range of -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Provides flexible voltage conversion capabilities including doubling and inversion using switched capacitor technology.
• Integrates a compact 8-pin VSSOP surface-mount package for efficient board space utilization.
• Operates reliably across a wide industrial temperature range without requiring external synchronous rectifiers.

Voltage Regulators - DC DC Switching Regulators Applications

• Portable battery-powered devices requiring negative supply rails
• LCD bias voltage generation
• RS-232 interface level shifting
• General-purpose DC-DC conversion in space-constrained electronics

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix (e.g., NOPB) against the datasheet to confirm lead-free status and environmental compliance. Ensure the VSSOP-8 package variant matches the design footprint. Confirm availability through authorized distributors as production status may vary by region.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 10 mA output is sufficient for the application. Consider the 6 kHz switching frequency for EMI sensitivity. Compare with adjustable variants like the LM2687 if variable output voltage is required instead of fixed ratios.

Voltage Regulators - DC DC Switching Regulators Part Context

Part of the LM2682 family of charge pumps designed for low-power applications. It serves as a cost-effective alternative to inductor-based converters for small current requirements. The MMX designation indicates the reel packaging format for automated assembly.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2682MM/NOPB: Identical electrical specifications but in tube packaging rather than reel. LM2682MX/NOPB: Same functionality in an SOIC-8 package. Verify pinout compatibility before substitution.
