Overview
The AS3824E-ZQFT is a four-channel LED lighting driver IC manufactured by ams OSRAM. It provides configurable constant current sources for RGB LEDs, with output currents adjustable from 20 mA to 150 mA via external resistors. The device operates without a microcontroller and features a switching frequency of 20 kHz. It is housed in a QFN-24 package suitable for surface mount technology. The component supports a power dissipation of 2 W and functions within an operating temperature range of -20°C to +85°C.
Feature Summary
- Four independent output channels designed for RGB LED applications
- Configurable output current ranging from 20 mA to 150 mA using external resistors
- Standalone operation capability eliminating the need for a microcontroller
- Logic level control interface for simplified integration
Applications
- RGB LED illumination systems
- LED lighting driver configurations
- Current sink applications for multi-color LED arrays
Procurement Notes
Verify the specific suffix ZQFT against the manufacturer's latest documentation to confirm packaging details and RoHS compliance status. Confirm availability as distribution listings may indicate discontinuation or regional sales restrictions. Ensure the QFN-24 footprint matches the target PCB design requirements before finalizing procurement decisions.
Selection Notes
Select this component when designing standalone LED drivers that require precise current regulation for multiple channels without complex digital control. The external resistor configuration allows flexibility in setting current levels between 20 mA and 150 mA. Consider the thermal management requirements given the 2 W power dissipation rating and the QFN-24 package constraints.
Part Context
This part belongs to the LED Lighting Drivers category under ams OSRAM's portfolio. It serves as a dedicated current sink solution for illuminating RGB LEDs. The device integrates regulator functionality to maintain stable output currents across the specified range, supporting efficient light emission in compact electronic assemblies.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with existing circuit designs if considering alternative components.
