LM2660-MWC

Voltage Regulators - DC DC Switching Regulators Overview

The LM2660-MWC is a switched capacitor voltage converter manufactured by Texas Instruments, belonging to the LM2660 series. It operates as a charge pump topology with a single output capable of delivering up to 100 mA. The device supports an input voltage range from 1.5 V to 5.5 V and provides fixed output configurations including -Vin, 2Vin, and Vin/2. It functions within a temperature range of -40°C to +85°C and utilizes a VSSOP-8 package.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Provides flexible voltage conversion ratios including inversion, doubling, and halving via fixed internal configuration.
• Integrates a shutdown function for power management efficiency.
• Operates without requiring external inductors, relying on external capacitors for energy storage.

Voltage Regulators - DC DC Switching Regulators Applications

• Generating negative supply rails from positive sources
• Creating dual polarity supplies from single inputs
• Voltage level shifting in low-power digital circuits

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix against official documentation to confirm pinout and electrical characteristics match design requirements. Confirm RoHS compliance status through current datasheets as manufacturing updates may occur. Ensure the VSSOP-8 package dimensions align with PCB footprint constraints before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when inductor-free solutions are required for moderate current applications up to 100 mA. Consider the fixed conversion ratios (-Vin, 2Vin, Vin/2) against variable frequency alternatives like the LM2662 if switching noise or frequency control is critical. Evaluate thermal performance within the specified operating temperature range.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2660 family of switched capacitor converters. It shares functional similarities with the LM2662 but differs in switching frequency and output current capabilities. The MWC suffix typically denotes a specific tape-and-reel packaging variant or material composition within the standard LM2660 product line.
