LC5222D

Overview

The LC5222D is an AC-DC offline switcher IC manufactured by Sanken Electric USA Inc., designed for LED driver applications. It integrates a power switch and control circuitry to support buck and boost topologies. The device operates within a supply voltage range of 25V to 200V and delivers a maximum output current of 400mA per channel. It features PWM dimming capability and includes an internal switch. The component is housed in an 8-SOP package with a width of 4.40mm, suitable for surface mount installation. It supports a wide operating temperature range from -40°C to 105°C.

Feature Summary

• Integrates AC-DC offline switching functionality with internal power switch
• Supports both buck and boost converter topologies for flexible LED driving
• Enables brightness control through PWM dimming interface

Applications

• LED lighting systems requiring AC-DC conversion
• General illumination applications using buck or boost architectures
• Offline LED drivers with PWM dimming requirements

Procurement Notes

Verify the specific suffix 'D' against official Sanken documentation to confirm package type and tape/reel specifications, as distribution data may list variants like 'S'. Confirm end-of-life status and lead times directly with the manufacturer or authorized distributors, as availability changes. Ensure the ordering part number matches the required thermal and electrical characteristics for the target application.

Selection Notes

Select the LC5222D when designing AC-DC LED drivers that require integrated switching and support for both buck and boost configurations. Consider its 400mA output current limit and 200V maximum supply voltage for appropriate load matching. Evaluate the 8-SOP package constraints for PCB layout and thermal management needs relative to the 105°C operating temperature rating.

Part Context

The LC5222D belongs to the LC5222 series of LED driver ICs from Sanken Electric. This family focuses on compact, integrated solutions for AC-DC powered LED applications. The 'D' suffix typically denotes a specific package variant within this series, distinct from other suffixes like 'S'. These components are engineered to simplify design by combining power switching and control functions in a single chip.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Verify compatibility with existing designs by comparing pinouts, electrical parameters, and thermal characteristics with alternative AC-DC LED driver ICs from Sanken or other manufacturers.
