LDS8711

Overview

The LDS8711 is a DC-DC regulator and LED driver IC manufactured by IXYS Integrated Circuits Division. It features a step-up (boost) topology with an internal switch capable of delivering 32mA output current. The device supports PWM dimming control for backlight applications. It operates within a supply voltage range of 2.7V to 5.5V and functions across a temperature range of -40°C to +85°C. The component is housed in an 8-TDFN (2x3) package with an exposed pad.

Feature Summary

• Integrates a boost converter topology with an internal power switch for efficient LED driving.
• Supports PWM dimming control for precise brightness adjustment in display backlights.
• Designed specifically for single-output LED driver applications.

Applications

• LED backlighting systems
• Portable electronic displays

Procurement Notes

Verify the specific suffix or tape-and-reel designation, as availability may vary between bulk packaging and reel formats. Confirm RoHS compliance status and REACH registration details against the latest manufacturer documentation before finalizing procurement specifications.

Selection Notes

Select this component for low-power backlight applications requiring a compact solution. Ensure the input voltage range aligns with the system's power supply rails. Verify that the 32mA output current meets the LED string requirements and that the thermal performance of the TDFN package is sufficient for the intended operating environment.

Part Context

The LDS8711 belongs to the LDS87xx series of LED drivers from IXYS Integrated Circuits Division. This family includes related models such as the LDS8710, LDS8720, LDS8724, and LDS8726, which share similar functional architectures but may differ in current ratings or specific feature sets.

Replacement Considerations

Publicly documented substitutes include the PAM2841GR from Diodes Incorporated. Verify pin compatibility and electrical parameter alignment when considering alternative components for design updates.
