ICL7662EBD+

Voltage Regulators - DC DC Switching Regulators Overview

The ICL7662EBD+ is a CMOS voltage converter manufactured by Analog Devices Inc./Maxim Integrated, housed in an SOIC-14 surface-mount package. It operates as a switched-capacitor charge pump with boost and inverting topologies. The device accepts an input voltage range of 4.5 V to 20 V and provides a single output capable of delivering up to 20 mA. The switching frequency is fixed at 10 kHz, and the unit supports an operating temperature range from -40°C to +85°C.
