Overview
The CAT661ELA is a high-frequency CMOS charge pump manufactured by onsemi, functioning as an inverter or voltage doubler. It provides a maximum output current of 100 mA and operates with a wide input voltage range from 2.7 V to 5.5 V. The device supports switching frequencies up to 3 MHz, enabling the use of small external capacitors for efficient power conversion. Packaged in an 8-pin SOIC format, it is designed for applications requiring compact solutions for generating negative voltages or doubling supply rails.
Feature Summary
- CMOS architecture ensures low quiescent current consumption during operation.
- Capable of functioning as either a voltage inverter or a voltage doubler circuit.
- Supports high-frequency switching to minimize external component size.
Applications
- Generating negative bias voltages for analog circuits
- Level shifting for RS-232 communication interfaces
- Powering LCD bias generation circuits
Procurement Notes
Verify the specific revision level against the manufacturer's datasheet MD-5003, as historical documentation may vary. Confirm that the 8-pin SOIC package matches the design footprint requirements. Ensure the operating environment stays within the specified temperature and voltage limits defined in the official specifications.
Selection Notes
Select this component when a compact solution for voltage inversion or doubling is required without the complexity of inductor-based converters. The CMOS technology makes it suitable for battery-powered devices where efficiency at light loads is critical. Evaluate the 100 mA output limit to ensure it meets the load current demands of the target application.
Part Context
This part belongs to the CAT661 family of charge pump ICs from onsemi (formerly Catalyst Semiconductor). These devices are specialized PMIC components designed for simple, cost-effective voltage conversion tasks in portable electronics and industrial control systems where space is constrained.
Replacement Considerations
Check for updated revisions within the CAT661 series. Verify pin compatibility if considering alternative charge pump ICs from other manufacturers. Ensure the replacement maintains the same 8-pin SOIC package and electrical characteristics.
