AS1111A-BWLT

Overview

The AS1111A-BWLT is a linear LED driver IC manufactured by ams OSRAM. It features two independent output channels, each capable of delivering up to 80mA. The device supports both analog and PWM dimming methods for precise brightness control. It operates within a supply voltage range of 0.15V to 3.6V and functions reliably across an ambient temperature range of -40°C to +85°C. The component is housed in a compact 6-WLCSP package with dimensions of 1.17mm x 0.77mm.

Feature Summary

Dual-channel linear current regulation with integrated internal switches
Supports simultaneous analog and PWM dimming for flexible brightness adjustment
Ultra-low minimum operating voltage enabling efficient power management

Applications

LED backlighting systems
General illumination circuits

Procurement Notes

Verify the End-of-Life (EOL) status prior to procurement, as this component has been officially discontinued. Confirm that alternative sourcing options or last-time buy windows are available through authorized distributors. Ensure that the specific WLCSP packaging requirements align with your manufacturing capabilities and that moisture sensitivity level constraints are strictly observed during handling.

Selection Notes

Select this component when designing low-voltage LED applications requiring dual-channel control. It is suitable for space-constrained designs due to its small WLCSP footprint. Consider the 80mA per channel limit and the linear topology efficiency characteristics against switching alternatives. Verify compatibility with system supply voltages between 0.15V and 3.6V.
