TC62D902FG,C,8,EL

Overview

The TC62D902FG,C,8,EL is a single-channel LED lighting driver IC manufactured by Toshiba Semiconductor and Storage. It operates as an offline switcher with integrated Power Factor Correction (PFC) capabilities, designed for AC-DC conversion applications. The device supports TRIAC dimming functionality and utilizes a flyback topology. Key electrical parameters include a maximum power dissipation of 1.38 W, a supply voltage range of 25 V, and a switching frequency of 200 kHz. The output provides a constant current of 10 mA in both high and low states. The component is housed in an 8-pin SOP package and is available in reel, cut tape, and MouseReel packaging formats.

Feature Summary

Procurement Notes

Verify the specific ordering suffix and full part number against official Toshiba documentation to ensure correct configuration. Confirm RoHS compliance status through the manufacturer's latest datasheet or certification documents. Check for end-of-life or obsolescence notices, as availability may be restricted. Ensure the selected packaging format matches production requirements. Cross-reference the pinout and thermal specifications with the official schematic guidelines before integration.

Selection Notes

Select this component for applications requiring integrated PFC and TRIAC dimming in a compact SOP-8 package. Evaluate the 10 mA constant current output against the target LED string requirements. Consider the 200 kHz switching frequency for EMI management and transformer design. Verify that the 25 V supply voltage range aligns with the system's input conditions. Assess the 1.38 W power dissipation limit for adequate thermal management within the enclosure.
