Overview
The BD60A00NUX-TR is a single-channel LED driver IC designed for white LED lighting applications. It functions as a boost DC/DC converter capable of driving up to 11 LEDs in series with a maximum current of 30mA. The device operates within an input voltage range of 2.7V to 5.5V and utilizes a typical switching frequency of 600kHz. It features a low quiescent current of 0.1µA typ and includes a soft start function with a typical duration of 1ms. The component is housed in a VSON-8 package.
Feature Summary
- Boost DC/DC converter architecture for stable constant current LED drive
- Supports brightness control via external PWM signals or DC input
- Separates IC power supply from coil power supply to widen input range
Applications
- White LED lighting systems requiring up to 11 series-connected LEDs
- Applications utilizing PWM brightness control between 100Hz and 30kHz
- Devices requiring high-speed response and direct current connection without electric tolerance
Procurement Notes
Verify the specific suffix -TR indicates tape and reel packaging when ordering. Confirm the operating temperature range aligns with system requirements, typically spanning -40°C to +85°C. Ensure the design accommodates the specified input voltage limits and output current constraints for reliable operation.
Selection Notes
Select this component for designs requiring a compact solution for driving multiple series LEDs from a low-voltage source. The separation of power supplies allows flexibility in input voltage ranges. Consider the 600kHz switching frequency for inductor selection and the 1ms soft start to manage inrush currents during startup phases.
Part Context
This part belongs to the BD60A series of LED drivers from Rohm Semiconductor. It is specifically configured for higher LED counts compared to variants like the BD60A60NUX, which supports up to 6 LEDs. The series emphasizes stability and high-speed response through current mode control.
Replacement Considerations
The BD60A60NUX is a related variant within the same family but is limited to a maximum of 6 LED lightings. Verify if the reduced LED capacity meets the application needs before substituting.
