LM2665M6/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2665M6/NOPB is a switched capacitor voltage converter manufactured by Texas Instruments, designed for efficient power management in compact applications. It operates within an input voltage range of 2.5V to 5.5V and delivers a maximum output current of 40mA. The device supports multiple conversion ratios, including voltage doubling (2Vin) and halving (Vin/2), making it versatile for various rail requirements. Operating at a fixed switching frequency of 80kHz, it utilizes a charge pump topology without synchronous rectification. The component is housed in a surface-mount SOT-23-6 package and is rated for operation across a junction temperature range of -40°C to 85°C.
