LT1054CP TI Switched Capacitor Voltage Converter | 8-PDIP | Input 3.5V-15V, Output -3.5V to -15V

Product Overview

The LT1054CP from Texas Instruments is a monolithic, bipolar, switched-capacitor voltage converter and regulator. It provides a regulated output voltage that is the negative of the input voltage, with a typical conversion efficiency of 99.9%. The device operates over a wide input voltage range of 3.5V to 15V and can deliver up to 100mA output current. Housed in an 8-pin PDIP package, the LT1054CP is ideal for applications requiring a negative voltage supply from a positive input.
