LM2682MM

Voltage Regulators - DC DC Switching Regulators Overview

The LM2682MM is a switched capacitor voltage doubler and inverter from Texas Instruments, housed in an 8-VSSOP package. It operates within an input voltage range of 2 V to 5.5 V, delivering a fixed output current of 10 mA. The device generates negative outputs relative to the input (specifically -Vin or -2Vin) with a maximum output voltage capability of -11.6 V. It functions at a switching frequency of 6 kHz and maintains a quiescent current of 150 uA. The component supports an operating temperature range from -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and RoHS compliance status. Ensure the ordering part number matches the required tape and reel or cut tape configuration. Confirm that the 8-VSSOP footprint aligns with the PCB design constraints before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a simple, low-current negative voltage source is needed from a single positive rail. It is suitable for applications where space is limited due to the small VSSOP package. Consider the 10 mA output limit and 6 kHz switching frequency when designing filter components for the output stage.
