LM2665M6X

Voltage Regulators - DC DC Switching Regulators Overview

The LM2665M6X is a switched capacitor voltage converter manufactured by Texas Instruments, housed in a SOT-23-6 surface-mount package. It operates with an input voltage range of 2.5 V to 5.5 V and provides a single output capable of delivering up to 40 mA. The device utilizes a charge pump topology with a fixed switching frequency of 80 kHz. Output voltages are configurable as either double the input voltage (2Vin) or half the input voltage (Vin/2), resulting in a selectable output range of 5 V to 11 V. It functions within a junction temperature range of -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates a charge pump topology for efficient voltage conversion without requiring external inductors.
• Provides flexible output configuration options allowing selection between doubled or halved input voltage ratios.
• Operates at a fixed switching frequency to simplify external component selection and reduce electromagnetic interference.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the complete part number including suffixes such as NOPB when sourcing components to ensure compliance with specific regulatory standards like RoHS. Confirm package type and tape-and-reel specifications match assembly requirements. Cross-reference manufacturer documentation for any recent product change notifications or pin marking updates that may affect integration.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing circuits that require moderate current drive from a switched capacitor architecture. Ensure the application input voltage falls within the specified 2.5 V to 5.5 V range to maintain proper operation. Consider the 40 mA output limit when sizing external capacitors and planning load requirements for the target voltage ratio.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM2665 series of switched capacitor voltage converters from Texas Instruments. It shares functional similarities with other parts in the family but is distinguished by its specific output current capability and package configuration. The series is designed for applications where inductor-based solutions are impractical due to size constraints.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The LM2665M6X/NOPB serves as a lead-free and RoHS-compliant alternative to earlier versions of the LM2665M6X. Verify pin compatibility and electrical specifications before substituting older non-NOPB variants in existing designs.
