Overview
The AL8823S-13 is a single-stage boost LED controller designed for MR16 and AR111 lamps. It operates from an AC/DC offline supply with a minimum voltage of 5V and maximum of 36V. The device features a switching frequency up to 1MHz, enabling compact inductor designs. It provides accurate constant current output and supports dimming capabilities. The component is housed in an 8-SOIC package with a width of 3.90mm and functions within a temperature range of -40°C to 105°C.
Feature Summary
- Delivers accurate constant current for LED lamps using a proprietary control scheme
- Compatible with commonly used electronic transformers for high power factor and low total harmonic distortion
- Supports dimmable applications for MR16 and AR111 form factors
- Enables small size inductors through operation frequencies up to 1MHz
Applications
- MR16 LED lamp drivers
- AR111 LED lamp drivers
- Dimmable LED lighting systems
- Electronic transformer compatible LED circuits
Procurement Notes
Verify the specific suffix 'S-13' against the manufacturer's official documentation to confirm package type and tape/reel specifications. Confirm end-of-life status as some sources indicate scheduled obsolescence. Ensure compatibility with external MOSFET requirements for intended output power levels before procurement.
Selection Notes
Select this component for designs requiring high power factor and low THD in MR16 or AR111 applications. The 1MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Ensure the design accommodates the 8-SOIC package dimensions and thermal requirements for the specified operating temperature range.
Part Context
The AL8823 series consists of boost controllers tailored for single-stage AC/DC LED drivers. The AL8823S-13 variant specifically targets retrofit lamp replacements where compatibility with existing electronic transformers is critical. It integrates control logic to manage boost topology without an internal switch, requiring an external MOSFET for power handling.
Replacement Considerations
Check for direct pin-to-pin substitutes within the AL8823 family or similar Diodes Incorporated boost controllers. Verify that any replacement maintains compatibility with electronic transformers and supports the required dimming protocols.
