LX1741CLM

DC DC Switching Controllers Overview

The LX1741CLM is a boost DC-DC switching regulator controller manufactured by Microsemi. It operates within an input voltage range of 3V to 28V and supports output voltages up to 60V. The device features a fixed operating frequency of 500kHz and includes integrated soft-start functionality. It utilizes an 8-MLP (3x3) surface-mount package.

DC DC Switching Controllers Feature Summary

• Integrated control circuitry for high-efficiency boost converter topologies
• Built-in soft-start mechanism to limit inrush current during startup
• Fixed-frequency operation ensuring stable switching performance

DC DC Switching Controllers Applications

• Portable electronic devices requiring step-up power conversion
• Industrial equipment with varying input voltage requirements
• Automotive electronics systems needing regulated power supplies

DC DC Switching Controllers Procurement Notes

Verify the specific manufacturer source, as Microsemi was acquired by Microchip Technology Inc. Confirm that the component designation aligns with current Microchip product lines. Ensure the 8-MLP package dimensions match your PCB footprint requirements before finalizing procurement orders.

DC DC Switching Controllers Selection Notes

Select this controller when designing boost converters requiring a wide input voltage range up to 28V. The fixed 500kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 60V maximum output capability when sizing downstream filtering components.

DC DC Switching Controllers Part Context

This component belongs to the family of power management ICs designed for efficient DC-DC conversion. It serves as a core control element in switch-mode power supplies, distinct from linear regulators or other topology controllers like buck or SEPIC designs.

DC DC Switching Controllers Replacement Considerations

Consult Microchip Technology Inc. official documentation for direct cross-reference part numbers. Verify pin compatibility and electrical specifications against any potential substitute components to ensure system integrity.
