Overview
The LX1675CLQ is a Power Management Integrated Circuit (PMIC) from Microsemi Corporation, designed for complex electronic systems. It features a multi-output configuration with four independent channels: three synchronous step-down converters and one Low Dropout (LDO) regulator. The device operates at a switching frequency of 600kHz and is housed in a 38-MLPQ (5x7) package.
Feature Summary
- Integrates three synchronous buck converters and one LDO for comprehensive power management
- Designed for high-reliability applications requiring stable voltage regulation
- Supports surface mount installation in compact form factors
Applications
- Controller systems
- Intel VRM (Voltage Regulator Module) applications
Procurement Notes
Verify the manufacturer part number against official Microsemi documentation to ensure authenticity. Confirm that the specific suffix 'CLQ' matches the required temperature range and packaging specifications. Cross-reference the 38-MLPQ package dimensions with your PCB footprint design to ensure mechanical compatibility before procurement.
Selection Notes
Select this component when a single IC solution is needed to provide multiple regulated voltages for controller or VRM architectures. Ensure the input voltage range and output current requirements align with the three buck and one LDO channel capabilities. Verify that the operating temperature range meets the environmental conditions of the target application.
Part Context
This PMIC belongs to the Microsemi family of high-performance analog and mixed-signal integrated circuits. These devices are engineered for managing and controlling power in demanding environments. The LX1675 series specifically targets applications requiring efficient power conversion and regulation within a small footprint.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult Microsemi technical support or authorized distributors for qualified alternatives if this specific part number is unavailable.
