LX1993CDU

LED Driver IC Overview

The LX1993CDU is a single-output DC-DC boost regulator designed for LED driving applications. It functions as an analog and PWM dimmable driver with a regulated output current of 300mA. The device utilizes a step-up (boost) topology to manage power delivery efficiently. It operates within a temperature range of 0°C to 70°C and is housed in an 8-MSOP surface-mount package.

LED Driver IC Feature Summary

• Supports both analog and PWM dimming control methods
• Provides regulated constant current output for LED loads
• Utilizes a compact 8-MSOP surface-mount package

LED Driver IC Applications

• LED backlighting systems
• General LED driving circuits
• Portable electronic display illumination

LED Driver IC Procurement Notes

Verify the manufacturer designation, as the component may be listed under Microsemi Corporation or its successor, Microchip Technology. Confirm the specific suffix (e.g., -T for tape and reel) matches the required packaging format. Ensure the part number corresponds to the 8-MSOP package variant. Check availability status, as older revisions may be discontinued or subject to long lead times from authorized distributors.

LED Driver IC Selection Notes

Select this component when a compact, single-channel boost regulator is required for low-power LED applications. It is suitable for designs needing precise current regulation without complex external feedback networks. Consider the operating temperature range and package size constraints. Verify compatibility with the system's input voltage range and dimming signal requirements before integration into the final product design.

LED Driver IC Part Context

This component belongs to the family of PMIC LED drivers produced by Microsemi, which was acquired by Microchip Technology. These devices are engineered for efficient power management in portable electronics. The LX1993 series specifically targets applications requiring simple, cost-effective solutions for driving white LEDs in displays and indicators.

LED Driver IC Replacement Considerations

Consult official Microchip documentation for confirmed substitute part numbers. Cross-reference pinouts and electrical specifications carefully. Generic equivalents may not support the same dimming features or current regulation accuracy.
