ICL7660ACBAZA-T

Product Overview

The ICL7660ACBAZA-T from Renesas Electronics Corporation is a charge pump switching regulator IC for generating a single fixed output from a 1.5V to 12V input. It can produce a positive or negative output at -Vin or 2Vin and provides up to 45mA of output current. The device uses a 3kHz switching frequency, has no synchronous rectifier, and uses an 8-SOIC surface-mount package for operating temperatures from 0°C to 70°C.

Key Features

• Charge pump topology with one fixed output.
• Input voltage range from 1.5V to 12V.
• Output voltage of -Vin or 2Vin.
• 45mA output current and 3kHz switching frequency.
• No synchronous rectifier.
• 8-SOIC (0.154 in, 3.90 mm width) surface-mount package.
• Operating temperature from 0°C to 70°C (TA).

Applications

• Generating a negative rail from a positive supply for low-current analog bias circuits.
• Creating a doubled positive rail from a single supply input for low-current loads.
• Providing a fixed charge-pump output in surface-mount power conversion designs.

Design & Procurement Notes

Designers should confirm that a fixed -Vin or 2Vin output is required, since the output is not adjustable. The 45mA output current and 3kHz switching frequency should be evaluated against the load and board layout. The 1.5V to 12V input range and 0°C to 70°C operating temperature define the supply and ambient conditions for the 8-SOIC surface-mount package.
