Overview
The LC5202D 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 features an internal switch. The device supports PWM dimming and delivers a maximum output current of 400mA. It operates within a supply voltage range of 25V to 400V and functions at a frequency of 200kHz. The component is housed in an 8-DIP package with through-hole mounting and is rated for an operating temperature range of -40°C to 105°C.
Feature Summary
- Integrates an internal switch for compact non-isolated buck topology designs
- Supports PWM dimming functionality for precise light control
- Designed specifically for direct connection to commercial AC power supplies
Applications
- Non-isolated LED lighting systems
- Commercial power supply driven LED drivers
- General illumination applications requiring AC-DC conversion
Procurement Notes
Verify the obsolete status of this component before integration, as it has been discontinued by the manufacturer. Confirm availability of alternative sources or final-time-buy options if production continuity is required. Ensure that any replacement strategy accounts for the specific electrical parameters and pinout compatibility of the LC5202D to maintain system performance.
Selection Notes
Select this IC for designs requiring a simple, non-isolated buck converter solution directly from AC mains. It is suitable for applications where cost and component count are critical, and where the specific 400mA output current aligns with LED string requirements. Consider the 8-DIP package constraints for PCB layout and thermal management in the final assembly.
Part Context
The LC5202D belongs to the LC5200 series from Sanken Electric, which focuses on power ICs for non-isolated LED drivers. This series is characterized by its buck topology and integration capabilities for commercial power supply applications. The LC5202D represents a specific variant within this family, offering fixed specifications for current and voltage handling tailored to standard LED lighting needs.
Replacement Considerations
The LC5202D is officially listed as obsolete. No public confirmed substitute part numbers are available in the provided documentation. Designers must evaluate end-of-life notices and consider redesigning with currently active components from the same or different manufacturers to ensure long-term supply chain stability.
