ICL7662CPA

Voltage Regulators - DC DC Switching Regulators Overview

The ICL7662CPA is a monolithic charge pump voltage inverter manufactured by Renesas Electronics Corporation. It converts positive input voltages ranging from +4.5V to +20V into corresponding negative output voltages of -4.5V to -20V. The device supports cascaded voltage multiplication, allowing for outputs defined as VOUT = -n x V+. It operates with a switching frequency of 10kHz and requires only two external capacitors. The component is housed in an 8-PDIP package with a through-hole mounting type and functions within a temperature range of 0°C to 70°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify component status as the ICL7662CPA is listed as discontinued. Confirm availability through authorized distributors or secondary markets. Ensure compatibility with existing PCB footprints for 8-PDIP packages. Check for RoHS compliance variations in replacement stock. Validate that the specific batch meets required operating temperature specifications for the intended application environment.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a simple, low-component-count solution for generating negative voltages from a positive source is required. It is suitable for applications where moderate current is not critical. Consider the ICL7660 series if lower input voltage ranges are needed. Evaluate the need for cascaded stages if output voltages exceed standard single-stage inversion capabilities. Ensure the load requirements align with the charge pump's impedance characteristics.

Voltage Regulators - DC DC Switching Regulators Part Context

The ICL7662 belongs to the ICL7660 family of super voltage converters. It shares pin compatibility with the ICL7660 but offers an extended input voltage range up to 20V. This family utilizes CMOS technology to achieve high efficiency without inductors. The device represents a legacy solution for analog signal conditioning and power management in older electronic designs.
