Renesas ICL7660S DC-DC Voltage Converter SOIC-8 1.5V to 12V Input

Renesas ICL7660S DC-DC Voltage Converter is a high-efficiency, monolithic DC-DC voltage converter that transforms a positive input supply of 1.5 V to 12 V into a complementary negative output of -1.5 V to -12 V, with a maximum output current of 45 mA. Housed in a compact SOIC-8 package, it suits designs that need a negative rail generated from a positive supply.

Overview

The ICL7660S integrates a series DC power supply regulator, an RC oscillator, a voltage level translator, and four output power MOS switches into a single SOIC-8 device. It requires only two non-critical external capacitors to perform both charge pump and charge reservoir functions, which simplifies circuit design and reduces component count.

Key Features

• Power efficiency of 98% at a load (RL) of 5 kΩ
• Open-circuit voltage conversion efficiency of 99.9%
• Integrated frequency boost pin for lower output impedance when using smaller external capacitors
• Enhanced SCR latch-up protection for increased reliability
• Converts a standard +5 V logic supply to ±5 V rails
• Pin-compatible replacement for the ICL7660 and other second-source devices
• Maximum oscillator frequency of 35 kHz
• Operating temperature range of 0°C to 70°C

Configurations

Beyond simple inverting operation, the device can be connected as a voltage doubler, generating up to 22.8 V from a 12 V input. It can also be configured for voltage multiplier or voltage divider applications, offering flexibility across a range of power management needs.

Choose the Renesas ICL7660S DC-DC Voltage Converter when you need a compact SOIC-8 voltage converter that supplies a negative rail from a positive input, or a pin-compatible drop-in for existing ICL7660 designs.
