LDS8724

Overview

The LDS8724 is a single-output DC-DC regulator IC designed for LED driver applications, manufactured by IXYS Integrated Circuits Division. It utilizes a boost converter topology with an internal switch capable of handling 1.9A switching current. The device operates on a supply voltage range of 2.7V to 5.5V and supports PWM dimming control at a frequency of 1MHz. Packaged in an 8-TDFN (2x3) surface-mount case with an exposed pad, it functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a boost converter topology with an internal power switch for compact LED driving solutions.
• Supports pulse-width modulation (PWM) dimming for precise brightness control.
• Designed specifically for backlight regulation applications.

Applications

• LED backlight regulation
• Portable electronic display illumination

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm package integrity and pin alignment against the 8-TDFN specification before integration. Ensure replacement components meet identical electrical and thermal requirements for system compatibility.

Selection Notes

Select this component for low-voltage LED backlighting systems requiring integrated boost conversion. Evaluate input voltage constraints against the 2.7V minimum requirement. Consider the 1.9A internal switch limit when sizing external inductors and output capacitors for target LED string currents.

Part Context

This part belongs to the IXYS Integrated Circuits Division portfolio of power management solutions. It represents a specialized linear-regulator-free approach for LED drivers, combining power stage and control logic in a small footprint suitable for space-constrained consumer electronics.
