LC5226D

Overview

The LC5226D is an AC/DC offline switcher LED driver IC manufactured by Sanken Electric USA Inc. It features a single output capable of delivering up to 800mA, supporting both step-down (buck) and step-up (boost) topologies. The device operates with PWM dimming and includes an internal switch. It supports a supply voltage range from 25V to 400V and functions within a temperature range of -40°C to 105°C. The component is housed in an 8-DIP package.

Feature Summary

• Supports non-isolating AC/DC offline switching applications
• Integrates high-voltage capability for direct connection to wide supply voltages
• Enables simple circuit design through integrated internal switching

Applications

• Non-isolating LED lighting systems
• AC/DC LED drivers requiring buck or boost topology
• General illumination applications utilizing PWM dimming

Procurement Notes

Verify the specific suffix 'D' corresponds to the 8-DIP through-hole package variant. Confirm current availability status as the product line may be subject to discontinuation notices. Ensure compatibility with required operating temperatures and input voltage ranges before integration.

Selection Notes

Select this component for designs requiring a non-isolating solution with high voltage tolerance up to 400V. It is suitable for applications needing a single channel with 800mA output capability. Consider the 8-DIP package for through-hole mounting requirements.

Part Context

This part belongs to the LC5220 series of non-isolating LED drivers. The series is characterized by simple and efficient designs that allow direct connection to various supply voltages due to their high voltage capabilities. It serves as an alternative to other variants within the same family with different packages or current ratings.

Replacement Considerations

LC5226S is the surface-mount equivalent in the same series. LC5222D offers similar functionality but with a lower 400mA output current rating.
