Renesas ICL7660A CMOS DC/DC Adjustable Voltage Converter 1.5-12V Input

Renesas ICL7660A CMOS DC/DC Voltage Converter converts a positive input of +1.5V to +12.0V into a complementary negative output of -1.5V to -12.0V, making it suitable for generating bipolar power rails from a single supply.

Overview

The Renesas ICL7660A is a monolithic CMOS power supply circuit designed for efficient and straightforward power management. It converts a positive input voltage into a complementary negative output and can generate bipolar (±) power rails from one supply, for example converting a standard +5V logic supply into ±5V. Its design requires only two non-critical external capacitors to perform its charge pump and charge reservoir functions, removing the need for complex inductor-based circuits.

Key Features

• Typical power efficiency of 98%, with a typical open-circuit voltage conversion efficiency of 99.9%
