ICL7660ACPA

Voltage Regulators - DC DC Switching Regulators Overview

The ICL7660ACPA is a CMOS charge pump DC-DC switch regulator manufactured by Renesas Electronics Corporation. It operates with an input voltage range of 1.5V to 12V and provides fixed output configurations of -Vin or 2Vin. The device delivers a maximum output current of 45mA in a single-output topology. It utilizes a non-synchronous rectifier architecture with a switching frequency of 3kHz. The component is housed in an 8-PDIP package (0.300", 7.62mm) designed for through-hole mounting. It supports operation within a temperature range of 0°C to 70°C.
