BD65D00MUV-E2

Overview

The BD65D00MUV-E2 is a four-channel white LED driver IC manufactured by ROHM Semiconductor, designed for backlight applications. It utilizes a boost topology with an integrated MOSFET and supports analog and PWM dimming. The device operates within a supply voltage range of 4.5 V to 27 V, delivering up to 100 mA per channel. It features a switching frequency of 1.25 MHz and can generate output voltages up to 41 V. Packaged in a 28-VQFN (VQFN028V5050) format, it functions reliably across temperatures from -40°C to +85°C.

Feature Summary

• Integrates a high-efficiency boost DC/DC converter with internal power FETs to minimize external component count.
• Supports precise brightness control through both analog voltage input and pulse-width modulation (PWM) signals.
• Provides independent current regulation for four distinct LED channels to ensure uniform illumination.

Applications

• LCD backlight drivers for portable electronic devices
• White LED lighting systems requiring multi-channel regulation
• Display modules in consumer electronics

Procurement Notes

Verify the specific suffix E2 confirms RoHS compliance and halogen-free status against the manufacturer's latest documentation. Confirm the package marking matches the VQFN028V5050 specification. Ensure the ordering quantity aligns with the standard factory pack size of 2,500 units or available cut-tape options. Cross-reference the datasheet revision date to guarantee compatibility with current design requirements.

Selection Notes

Select this component when designing circuits requiring four independent LED channels driven by a single boost regulator. It is suitable for systems needing a wide input voltage range up to 27 V. Consider the thermal performance of the VQFN package if operating near maximum current limits. Verify that the required dimming interface matches either analog or PWM capabilities provided by the IC.
