CL88020T-E/SE

Overview

The CL88020T-E/SE is a sequential linear LED driver IC designed for offline AC-DC applications. It features an internal MOSFET switch and supports four independent output taps. The device operates with an input voltage range of 90V to 135V and delivers a maximum output current of 130mA per tap. It is housed in an 8-SOIC package with an exposed pad, suitable for surface mount mounting. The component is rated for junction temperatures between -40°C and 125°C.

Feature Summary

• Sequential linear regulation architecture for multi-segment LED control
• Integrated high-voltage MOSFET switch for simplified circuit design
• Four independent output taps for segmented lighting applications

Applications

• LED lighting systems requiring sequential segment control
• Offline AC-DC power supplies for solid-state lighting
• General illumination fixtures utilizing linear LED drivers

Procurement Notes

Verify the specific suffix /SE against the manufacturer's latest datasheet to confirm tape-and-reel packaging specifications. Ensure the ordering part number matches the exact pinout and thermal pad requirements for your PCB layout. Cross-reference the official Microchip documentation for any recent revisions or compliance updates before finalizing procurement.

Selection Notes

Select this component when designing offline LED drivers that require sequential tap management without external switching components. The integrated MOSFET reduces bill-of-materials count. Verify that the required input voltage falls within the 90V to 135V operational window and that the thermal dissipation capabilities of the 8-SOIC package meet the system's thermal constraints.

Part Context

This part belongs to Microchip's family of sequential linear LED drivers. These devices are engineered for cost-effective, high-reliability lighting solutions where precise current regulation across multiple segments is necessary. The series typically targets general lighting markets by simplifying the design of offline power stages through integrated switching elements.

Replacement Considerations

Consult Microchip's official substitution guide for verified equivalents. Do not assume functional compatibility with other LED driver families due to differences in tap sequencing logic and internal MOSFET characteristics.
