Overview
The LC5203D is an AC/DC offline switcher LED driver IC manufactured by Sanken Electric USA Inc. It utilizes a step-down (buck) topology to regulate current for single-output LED applications. The device supports PWM dimming and delivers a maximum output current of 800mA. It operates within a supply voltage range of 25V to 400V and functions at a switching frequency of 200kHz. The component features an internal switch and is housed in an 8-DIP package with seven active leads, designed for through-hole mounting.
Feature Summary
- Integrates an internal power switch for compact offline AC/DC conversion
- Supports pulse-width modulation (PWM) dimming control
- Provides regulated constant current output for LED strings
Applications
- Offline AC/DC LED lighting systems
- General illumination fixtures requiring buck topology
- LED drivers utilizing through-hole DIP packaging
Procurement Notes
Verify the specific suffix 'D' against the manufacturer's official documentation to confirm pinout and package dimensions. Note that this product may be listed as obsolete or end-of-life in distributor catalogs; check current availability status directly with Sanken Electric or authorized agents before design finalization.
Selection Notes
Select this component for designs requiring a simple buck converter architecture with integrated switching capabilities. Ensure the input voltage range aligns with the 25V to 400V specification. Confirm that the 800mA output current meets the target LED array requirements and that the 8-DIP package fits the intended PCB layout constraints.
Part Context
The LC5203D belongs to the LC5200 series of off-line DC/DC LED driver ICs from Sanken Electric. This series is designed for cost-effective, high-reliability LED driving solutions. The device simplifies circuit design by combining the controller and power switch into a single package, reducing external component count compared to discrete solutions.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided data. Check for direct replacements within the LC5210 or LC5223 series if compatible, but verify electrical parameters and pin compatibility independently.
