LM2660MM

Voltage Regulators - DC DC Switching Regulators Overview

The LM2660MM/NOPB is a switched capacitor voltage converter manufactured by Texas Instruments, designed for generating negative output voltages from positive input sources. It operates within an input voltage range of 1.5 V to 5.5 V and provides a fixed output current capability of 100 mA. The device utilizes a charge pump topology with a typical switching frequency of 40 kHz. It supports output voltages ranging from -5.5 V to -1.5 V relative to the input. The component is housed in an 8-pin VSSOP package and is rated for operation across a temperature range of -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix (e.g., NOPB) against the datasheet to confirm RoHS compliance and lead-free status. Ensure the package variant matches the required footprint, as the MM suffix denotes VSSOP-8. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and traceability. Check for any recent product change notifications that may affect specifications or availability.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution for generating negative voltage is required from a single positive supply rail. Consider the 100 mA output current limit and 40 kHz switching frequency for noise-sensitive applications. Evaluate the VSSOP-8 package size constraints against board space requirements. Compare performance metrics such as quiescent current and efficiency against alternative charge pump regulators if low-power standby modes are critical.

Voltage Regulators - DC DC Switching Regulators Part Context

The LM2660 belongs to Texas Instruments' family of switched capacitor voltage converters. It is distinct from linear regulators and inductive DC-DC converters, offering a passive-component-based solution for voltage inversion. The MM package variant specifically refers to the small-outline VSSOP form factor, differentiating it from SOIC or other package types within the same electrical specification family.
