LM2766M6X/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2766M6X/NOPB is a switched capacitor voltage doubler manufactured by Texas Instruments, formerly National Semiconductor. It operates with an input voltage range of 1.8 V to 5.5 V and provides an adjustable output voltage from 3.6 V to 11 V. The device delivers up to 20 mA of output current through a single output channel. It functions at a switching frequency of 200 kHz and consumes 350 µA of operating supply current. The component supports shutdown functionality and is housed in a SOT-23-6 package. It is rated for operation between -40°C and +85°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation as Texas Instruments on official datasheets, noting the historical National Semiconductor lineage. Confirm the specific suffix /NOPB indicates lead-free compliance and RoHS adherence. Ensure the SOT-23-6 package variant matches the required footprint for PCB layout. Cross-reference the 200 kHz switching frequency requirement with system noise constraints before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution is needed to boost low input voltages (1.8V–5.5V) to higher levels (up to 11V) with moderate current demands (20mA). The SOT-23-6 package offers space efficiency for portable designs. Consider the 200 kHz switching frequency for EMI compatibility and external component sizing. Verify that the load requirements do not exceed the specified 20 mA limit to ensure stable regulation and thermal performance within the industrial temperature range.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2766 series of switched capacitor regulators. It represents a transition period where National Semiconductor products were integrated into Texas Instruments' portfolio, often retaining the NS branding in legacy part numbers while being supported by TI documentation. The M6X suffix specifically denotes the SOT-23-6 surface-mount package configuration.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Consult official substitution guides for direct equivalents. Generic charge pumps may differ in current capacity or package dimensions. Verify pinout compatibility if replacing with other LM2766 variants or similar Texas Instruments switched capacitor regulators.
