ICL7660CBAZ-T

Product Overview

The ICL7660CBAZ-T from Renesas Electronics Corporation is a surface-mount charge pump switching regulator IC. It provides one fixed output and supports positive or negative regulation with -Vin or 2Vin output values. The input range is 1.5V to 10V, and the output current is 45mA. The 10kHz switching design has no synchronous rectifier and operates from 0°C to 70°C (TA) in an 8-SOIC, 3.90mm package.

Key Features

• Charge pump topology with one fixed output for positive or negative voltage conversion.
• 1.5V to 10V input range, 45mA output current, and 10kHz switching frequency.
• Ratiometric function, no synchronous rectifier, 0°C to 70°C (TA), and 8-SOIC surface-mount package.

Applications

• Generating a negative auxiliary rail from a positive input for circuits requiring a voltage below ground.
• Providing a 2Vin positive rail for low-current loads that need a higher voltage than the available input.
• Implementing compact surface-mount voltage conversion in designs constrained to the 0°C to 70°C operating range.

Design & Procurement Notes

When selecting the ICL7660CBAZ-T, confirm the input voltage stays between 1.5V and 10V and the load current stays at or below 45mA. The fixed -Vin or 2Vin output scales with input voltage, so it is not independently adjustable. Layout should account for the 10kHz charge pump switching and absence of synchronous rectification. Verify ambient conditions remain within 0°C to 70°C (TA) and the board supports the 8-SOIC, 3.90mm surface-mount footprint.
