MCP1662T-E/OT

LED Driver IC Overview

The MCP1662T-E/OT is a high-voltage step-up LED driver featuring a non-synchronous boost topology. It operates from an input voltage range of 2.4 V to 5.5 V and delivers up to 32 V output. The device supports a maximum output current of 200 mA at a fixed switching frequency of 500 kHz. Packaged in a compact SOT-23-5 surface-mount format, it includes UVLO and open load protection. It is qualified under AEC-Q100 standards for automotive applications.

LED Driver IC Feature Summary

• Integrated non-synchronous boost converter optimized for constant current LED string driving
• Built-in open LED protection and undervoltage lockout (UVLO) for system reliability
• Supports PWM dimming control for brightness adjustment
• Automotive-grade qualification ensuring robust performance in demanding environments

LED Driver IC Applications

• LED lighting driven by two or three alkaline batteries
• LED lighting powered by NiMH or NiCd battery packs
• LED strings powered by single lithium-ion or lithium-polymer cells

LED Driver IC Procurement Notes

Verify the specific suffix 'E/OT' corresponds to the required temperature grade and tape-and-reel packaging configuration. Confirm that the AEC-Q100 qualification aligns with your target application's environmental requirements. Ensure the SOT-23-5 footprint matches your PCB layout constraints before finalizing procurement.

LED Driver IC Selection Notes

Select this component when a compact, non-synchronous boost solution is needed for low-power LED strings. It is suitable for portable devices requiring operation from single-cell lithium or multi-cell alkaline sources. Consider the 200 mA current limit and 32 V output ceiling against your specific LED forward voltage and current demands.

LED Driver IC Part Context

This part belongs to Microchip's MCP1662 family of LED drivers. It shares core functionality with variants like the MCP1662T-E/MNY but differs in packaging and reel specifications. The family focuses on space-efficient, fixed-frequency boost conversion for portable lighting applications.

LED Driver IC Replacement Considerations

The MCP1662T-E/MNY is a documented alternative within the same product family. Verify package compatibility and reel specifications when substituting.
