LT1054CDWRG4

Voltage Regulators - DC DC Switching Regulators Overview

The LT1054CDWRG4 is a switched-capacitor voltage converter with an integrated regulator, manufactured by Texas Instruments. It operates within an input voltage range of 3.5V to 15V and provides a single adjustable output up to 26.4V. The device delivers a maximum output current of 100mA at a switching frequency of 25kHz. It utilizes a charge pump topology capable of generating positive or negative voltages relative to the input. The component is housed in a 16-SOIC package (0.295" width) and is rated for commercial operating temperatures from 0°C to 70°C.
