Overview
The BD9483FV-GE2 is a two-output LED lighting driver IC manufactured by Rohm Semiconductor. It utilizes a boost topology with an adjustable output voltage and operates within a supply voltage range of 11 V to 35 V. The device supports PWM dimming and functions at a switching frequency of 150 kHz. Packaged in a 24-pin SSOP-B format, it is designed for surface mount installation and operates reliably between -40°C and +85°C.
Feature Summary
- Supports dual-channel LED driving via a boost converter topology
- Enables precise brightness control through PWM dimming functionality
- Integrates protection mechanisms including over-voltage and short-circuit safeguards
Applications
- LED backlighting systems
- General LED lighting fixtures
- Commercial illumination equipment
Procurement Notes
Verify the current lifecycle status before procurement, as sources indicate this component may be classified as Not Recommended for New Designs (NRND). Confirm package authenticity and datasheet revisions directly with Rohm Semiconductor or authorized distributors to ensure compliance with specific project requirements and availability constraints.
Selection Notes
Select this component for designs requiring two independent LED channels driven by a single boost controller. Ensure the input power supply meets the minimum 11 V requirement and that the thermal environment remains within the specified operating temperature range. Verify compatibility with PWM dimming signals and check if the 24-SSOP-B package fits the board layout constraints.
Part Context
This part belongs to the BD9483 series of LED drivers from Rohm Semiconductor. It is distinct from other series like the BD9479 or BD9413, which offer different channel counts or package types. The BD9483 specifically targets applications needing dual outputs in a compact form factor without integrated power MOSFETs.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult official Rohm Semiconductor resources for potential obsolescence management or alternative recommendations.
