FT8870A-RT

Overview

The FT8870A-RT is an AC DC offline switcher IC designed for LED driver applications. It utilizes a step-down (Buck) topology and features an internal switch. The device supports a maximum supply voltage of 8V and operates within a temperature range of -40°C to 125°C TA. It is housed in an 8-SOP package with a width of 3.90mm. The component provides a single output channel capable of delivering up to 180mA. It is classified as an active product available in tape and reel packaging.

Feature Summary

• Integrates an internal high-voltage switch for simplified circuit design
• Supports dimming control functionality for LED brightness adjustment
• Operates as an offline switcher suitable for direct AC input conversion

Applications

• LED backlighting systems
• Offline AC-DC power supplies
• General lighting driver circuits

Procurement Notes

Verify the specific suffix 'A' against official datasheets to confirm current availability status, as some variants in this family may be obsolete. Confirm the 180mA output rating matches the target application requirements. Ensure the 8-SOP package dimensions align with the PCB footprint. Check for RoHS compliance documentation if required by the end product specifications.

Selection Notes

Select this component for designs requiring a Buck topology for LED driving from an AC source. The 180mA output current capability suits low-power LED arrays. The wide operating temperature range allows for use in environments with significant thermal variations. The integrated switch reduces external component count compared to discrete solutions.

Part Context

This part belongs to the FT8870 series of LED drivers from Fremont Micro Devices Ltd. The series includes variants such as the FT8870 and FT8870S, which share similar topologies but may differ in output current or packaging. The FT8870A-RT specifically denotes the version with 180mA output capability in the standard SOP package.
