AL1677-05BS-13

Overview

The AL1677-05BS-13 is an AC/DC offline switcher designed for LED lighting applications. It features a step-down (buck) topology with an integrated 0.5 A / 500 V MOSFET. The device operates on a universal AC input voltage range of 85 to 277 VAC. It delivers a constant output current of 500 mA at an output voltage of up to 15 V. The component is housed in a surface-mount package and supports operating temperatures from -40°C to +105°C.

Feature Summary

• Integrates a high-voltage power MOSFET within the IC package
• Supports universal AC input voltage ranges
• Provides regulated constant current output for LED strings

Applications

• LED lighting drivers
• Offline buck converter circuits
• General-purpose AC/DC power supplies

Procurement Notes

Verify the specific suffix 'BS' against the manufacturer's latest datasheet to confirm pinout and electrical characteristics, as suffixes often denote tape-and-reel packaging or specific thermal grades. Ensure the selected variant matches the required output current and voltage ratings for the target application design.

Selection Notes

Select this component for designs requiring a compact solution with an integrated power switch. The 500 mA output current capability suits low-power LED arrays. Verify that the external passive components are rated for the maximum input voltage and switching frequency to ensure reliable operation within the specified temperature range.

Part Context

This part belongs to the AL1677 series of LED driver ICs from Diodes Incorporated. These devices are engineered for cost-effective and space-constrained lighting solutions. The series typically offers high efficiency and simplified design due to the integration of control logic and power switching elements.

Replacement Considerations

The AL1676-40DS7-13 is a related device from the same manufacturer offering higher output current capabilities. When substituting, verify that the pin compatibility and thermal performance meet the design requirements.
