ICL7660ACBA

Voltage Regulators - DC DC Switching Regulators Overview

The ICL7660ACBA is a CMOS voltage converter IC manufactured by Harris Corporation, functioning as an inverting charge pump switch regulator. It operates within an input voltage range of 1.5V to 12V and provides a fixed negative output configuration. The device delivers a maximum output current of 45mA with a typical switching frequency of 10kHz. It is housed in an 8-SOIC package (0.154 inch width) designed for surface mount installation. The component supports commercial temperature ranges from 0°C to 70°C.
