DC Switching Voltage Regulators

LM2660M/NOPB Description

The LM2660M/NOPB from Texas Instruments is a high-performance, charge pump voltage inverter designed to generate a negative output voltage from a positive input supply. Operating within a 1.5V to 5.5V input range, it delivers a fixed inverted output with a maximum current capability of 100mA. This 8-SOIC packaged IC employs a ratiometric charge pump topology, eliminating the need for inductors and simplifying board design. With switching frequencies of 5kHz or 40kHz (selectable via an external clock), it offers flexibility for noise-sensitive or efficiency-optimized applications. The device is RoHS3 compliant and features a Moisture Sensitivity Level (MSL) 1 rating, ensuring reliability in harsh environments.
