Overview
The AS3665-ZWLT is a multi-output LED driver IC manufactured by ams-OSRAM USA INC. It integrates a switched capacitor (charge pump) topology to regulate DC voltage for driving multiple LED channels. The device supports I2C dimming control and operates with a specified output current of 20mA. It is housed in a compact 25-WLCSP package with dimensions of 2.5x2.5 mm, designed for space-constrained applications requiring precise LED regulation.
Feature Summary
- Integrates a switched capacitor charge pump topology for efficient DC-DC regulation
- Supports digital control via I2C interface for dimming functions
- Provides regulated output current for multi-channel LED driving
Applications
- Interior vehicle monitoring systems
- In-cabin sensing illumination
- Compact mobile device lighting
Procurement Notes
Verify the specific suffix 'ZWLT' against the manufacturer's official datasheet to confirm pinout compatibility and thermal characteristics. Ensure the design accommodates the 25-WLCSP footprint dimensions of 2.5x2.5 mm. Confirm that the I2C bus voltage levels match the system logic requirements before integration.
Selection Notes
Select this component when a small form factor is critical due to its WLCSP packaging. It is suitable for applications requiring precise current regulation at 20mA per channel. The integrated charge pump eliminates the need for external inductors, simplifying the PCB layout compared to inductive buck or boost converters.
Part Context
This part belongs to the ams-OSRAM portfolio of digital photonics solutions. The company specializes in light and sensor technologies for automotive, industrial, and medical sectors. The AS3665 series addresses the demand for miniaturized, high-efficiency drivers in modern electronic devices where space and power efficiency are paramount constraints.
Replacement Considerations
Consult official substitution guides for equivalent multi-output LED drivers with I2C interfaces. Verify that any alternative maintains the 2.5x2.5 mm package outline and 20mA output capability to ensure mechanical and electrical compatibility without redesigning the host circuit.
