Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2660M

LM2660M

Voltage Regulators - DC DC Switching Regulators Overview

The LM2660M is a switched-capacitor voltage converter manufactured by Texas Instruments, formerly National Semiconductor. It operates as an inverting charge pump with an input voltage range of 1.5 V to 5.5 V. The device provides a single output capable of sourcing up to 100 mA, generating voltages between -1.5 V and -5.5 V. It functions at a switching frequency of 40 kHz and includes a shutdown feature. The component is housed in an 8-pin VSSOP package and supports operation from -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Inverting charge pump topology for negative voltage generation
Integrated shutdown control for power management
Compact surface-mount packaging

Voltage Regulators - DC DC Switching Regulators Applications

RS-232 interface biasing
