LM2660M

Voltage Regulators - DC DC Switching Regulators Overview

The LM2660M is a switched-capacitor voltage converter manufactured by Texas Instruments, housed in an 8-SOIC package. It operates as a charge pump with a fixed output configuration capable of generating positive or negative voltages relative to the input, specifically -Vin, 2Vin, and Vin/2. The device supports an input voltage range from 1.5 V to 5.5 V and delivers a maximum output current of 100 mA. It features a switch frequency of 40 kHz and includes a shutdown function for power management. The component functions within a junction temperature range of -40°C to +85°C.
