BD6066EKN-E2

Overview

The BD6066EKN-E2 is an LED lighting driver IC designed for medium to large LCD applications with white backlighting. It operates within a supply voltage range of 2.7 V to 22 V and features a boost topology. The device supports four output channels with a maximum output current of 30 mA per channel. It functions at a switching frequency of 1 MHz and includes overvoltage protection. The component is housed in a 28-pin HQFN package with an exposed pad, suitable for surface mount installation.

Feature Summary

• Optimized for minimizing forward voltage drop in LED strings
• Integrates overvoltage protection for circuit safety
• Supports PWM dimming control for brightness adjustment

Applications

• White backlight drivers for medium LCD panels
• White backlight drivers for large LCD panels
• LED display driver circuits

Procurement Notes

Verify the specific suffix E2 indicates RoHS compliance and halogen-free status as per ROHM standards. Confirm the HQFN-28EP package dimensions against your PCB footprint requirements. Ensure the input voltage range aligns with your system's power supply rails before integration.

Selection Notes

Select this component when driving white LEDs in medium to large LCD backlights requiring high efficiency. The 1 MHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the thermal performance of the HQFN package if operating near maximum current limits.

Part Context

This part belongs to the BD6066 series of LED drivers from ROHM Semiconductor. It is specifically engineered for LCD backlight applications, distinguishing itself through optimized voltage drop characteristics and integrated protection features suitable for portable and industrial display systems.

Replacement Considerations

The BD6066GU-E2 is a related variant in the same series but utilizes a different package type. Verify pin compatibility and thermal dissipation capabilities when substituting between package styles.
