FT8870C-RT

Overview

The FT8870C-RT is an AC/DC offline switcher LED driver IC manufactured by Fremont Micro Devices Ltd. It utilizes a buck topology to regulate current for backlight applications. The device features an internal switch and supports dimming functionality. It operates within a supply voltage range of 5.3V to 8V and delivers a maximum output current of 280mA per channel. The component is housed in an 8-SOP package with a width of 3.90mm and is rated for operation between -40°C and 125°C.

Feature Summary

• Integrates an internal power switch for compact offline AC/DC conversion
• Supports dimming control for adjustable LED brightness
• Employs step-down (buck) topology for efficient energy regulation

Applications

• LED backlighting systems
• Offline AC/DC power supplies
• General illumination drivers

Procurement Notes

Verify the specific suffix 'C' against official datasheets, as it may denote distinct electrical characteristics or compliance status compared to other variants like the FT8870S-RT. Confirm RoHS compliance status, as some sources indicate non-compliance while others do not specify. Ensure the 280mA rating aligns with design requirements rather than assuming generic family performance.

Selection Notes

Select this component for designs requiring a single-output buck converter with integrated switching capabilities. The 8-SOP package suits surface-mount assembly constraints. Verify that the 280mA output current meets load demands and that the operating temperature range covers environmental conditions. Check compatibility with required dimming signals before finalizing the bill of materials.

Part Context
