LM2664M6X/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2664M6X/NOPB is a switched capacitor voltage converter manufactured by Texas Instruments, housed in a SOT-23-6 surface-mount package. It operates as a charge pump topology capable of generating positive or negative fixed output voltages relative to the input (specifically -Vin or 2Vin). The device supports an input voltage range from 1.8 V to 5.5 V and delivers an output current of up to 40 mA. It functions within a temperature range of -40°C to +85°C with a switching frequency of 80 kHz and a quiescent current of approximately 350 µA.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix configuration against the manufacturer's latest datasheet to ensure compatibility with required output polarity and packaging options. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region. Ensure the ordering part number matches the exact pinout and electrical specifications required for the target application design.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution is needed for generating inverted or doubled voltages from a low-voltage source. Consider the 40 mA output limit and 80 kHz switching frequency when evaluating filter requirements and load capabilities. Compare against similar charge pumps if higher current or different input voltage ranges are required for the specific system architecture.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM266x family of switched capacitor voltage converters from Texas Instruments. It shares architectural similarities with parts like the LM2665 and LM2766 but differs in specific output configurations and current capabilities. The family is designed for space-constrained applications where inductor-based DC-DC converters are impractical due to size or cost constraints.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other variants within the LM266x series such as the LM2665M6X/NOPB, though electrical parameters like output current and voltage range must be verified. Cross-reference with the LM2664MM/NOPB for alternative packaging options while maintaining identical electrical performance.
