KTD3118EAA-25-TR

Overview

The KTD3118EAA-25-TR is a two-channel LED driver IC manufactured by Kinetic Technologies, designed for LED lighting applications. It integrates a boost converter topology with EN and PWM control capabilities. The device supports an output current of 25 mA per channel and operates within an input voltage range of 2.7 V to 5.5 V. It features a fixed switching frequency of 800 kHz and includes 38 V overvoltage protection (OVP). The component functions reliably across a temperature range of -40°C to +85°C and is housed in a compact WLCSP-9 package.

Feature Summary

• Integrates a boost converter with dedicated enable and pulse-width modulation control interfaces
• Provides hardware-based overvoltage protection to safeguard connected LED loads
• Supports constant current regulation for dual-channel LED arrays

Applications

• LED backlighting systems
• Portable electronic device illumination
• General LED lighting modules

Procurement Notes

Verify the specific suffix '25' corresponds to the required 25 mA output current rating during procurement. Confirm that the WLCSP-9 package dimensions align with the target PCB layout constraints. Ensure the selected supplier provides official datasheets to validate the 38 V OVP threshold and 800 kHz switching frequency specifications before finalizing orders.

Selection Notes

Select this component when a dual-channel solution with integrated boost conversion is required for space-constrained designs. It is suitable for applications needing precise PWM dimming control alongside hardware enable signals. Consider the WLCSP-9 footprint if board real estate is limited. Verify that the 2.7 V to 5.5 V input range matches the system power supply architecture.
