Overview
The BD6590MUV-E2 is a standard boost LED lighting driver IC manufactured by ROHM Semiconductor. It features six independent output channels designed for white LED applications. The device operates within an input voltage range of 4.5 V to 5.5 V and supports a maximum output current of 30 mA per channel. It utilizes a boost topology with an integrated MOSFET and functions at a switching frequency of 1.25 MHz. The component is housed in a VQFN024V4040-40 package, suitable for surface mount installation. It is rated for operation between -40°C and +85°C, with a maximum power dissipation of 1.51 W.
Feature Summary
- Integrates a high-side switch MOSFET to reduce external component count
- Provides six independent constant current output channels for flexible LED string configurations
- Supports standard boost topology for efficient step-up voltage conversion
Applications
- White LED driver circuits
- LED lighting systems requiring multi-channel control
- Portable electronic devices utilizing LED illumination
Procurement Notes
Verify the current lifecycle status before procurement, as this component is marked as Not Recommended for New Designs (NRND). Confirm that the VQFN024V4040-40 package dimensions align with existing PCB footprints. Ensure compliance with RoHS requirements and moisture sensitivity levels specified in the official datasheet. Validate that the 4.5 V to 5.5 V input range matches the system power supply architecture.
Selection Notes
Select this component when designing LED drivers requiring six independent channels from a single IC. It is appropriate for applications needing a 1.25 MHz switching frequency and 30 mA output capability. Consider the thermal performance given the 1.51 W power dissipation limit in the VQFN package. Ensure the design accommodates the specific operating temperature range of -40°C to +85°C.
Part Context
This part belongs to the ROHM LED Lighting Drivers category, specifically under White LED Drivers. It is classified as a Driver IC within the PMIC family. The manufacturer identifies it as a standard boost type controller. The product line focuses on compact solutions for LED illumination using integrated power switches.
Replacement Considerations
The part number alias BD6590MUV refers to the same functional device without the environmental suffix. No other verified substitute part numbers are documented in the provided data.
