Overview
The LC5202S is an AC/DC offline switcher IC designed for non-isolated LED driver applications using commercial power supplies. It utilizes a step-down (buck) topology and supports PWM dimming. The device features an internal switch, operates within a supply voltage range of 25V to 400V, and delivers an output current of 400mA. It is housed in an 8-SOP surface-mount package with a width of 4.40mm and functions across a temperature range of -40°C to 105°C.
Feature Summary
- Integrates a main controller and internal switch for compact non-isolated LED driver designs
- Supports PWM dimming control for brightness adjustment
- Utilizes buck topology for efficient AC/DC conversion
Applications
- Non-isolated LED lighting systems powered by commercial AC mains
- LED drivers requiring PWM dimming capabilities
- Compact AC/DC offline switching power supplies
Procurement Notes
Verify component authenticity due to potential availability issues. Confirm the specific suffix 'S' corresponds to the 8-SOP package variant. Check for end-of-life status or alternative sourcing options as this series may be discontinued. Ensure compatibility with existing PCB footprints and thermal management requirements before procurement.
Selection Notes
Select this component for non-isolated buck converter LED applications requiring integrated switching. Verify input voltage ranges up to 400V and output current limits of 400mA match design specifications. Consider the 8-SOP package constraints for thermal dissipation and board space. Compare against other LC5200 series variants if isolation or different topologies are required.
Part Context
Part of the Sanken LC5200 series, which comprises power ICs featuring buck topology for non-isolated LED drivers connected to commercial power supplies. This series integrates main control functions and switches to simplify circuit design for AC/DC offline applications.
Replacement Considerations
Check for direct substitutes within the LC5200 series, such as LC5202D, noting package differences. Verify functional equivalence regarding topology, current rating, and dimming support before substitution.
