MCP1662T-E/MNY

LED Driver IC Overview

The MCP1662T-E/MNY is a fixed-frequency non-synchronous boost converter optimized for driving LED strings from two or three alkaline, NiMH/NiCd, or single lithium-ion/lithium-polymer cells. It operates with an input voltage range of 2.4 V to 5.5 V and delivers up to 200 mA output current at a maximum voltage of 32 V. The device features a 500 kHz switching frequency, 200 nA standby current, and -40°C to +125°C operating temperature range. Packaged in an 8-pin TDFN with exposed pad, it includes UVLO and open load protection.

LED Driver IC Procurement Notes

Verify the specific suffix MNY corresponds to the TDFN-8 package with reel/cut tape options as listed in official Microchip documentation. Confirm AEC-Q100 qualification status if automotive application is required. Ensure compatibility with 2.4V to 5.5V input ranges and 32V max output constraints during system design validation.

LED Driver IC Selection Notes

Select this component when designing compact LED drivers requiring high efficiency from low-voltage sources. The TDFN-8 package suits space-constrained designs. Consider the 500 kHz frequency for passive component size trade-offs. Verify thermal performance within the -40°C to +125°C range for target environment conditions.

LED Driver IC Part Context

Part of the MCP1662 family of high-voltage step-up LED drivers. The MCP1662 series offers non-synchronous boost conversion optimized for portable electronics. Variants like MCP1662T-E/OT provide alternative packaging (SOT-23) while maintaining identical electrical characteristics and functionality for flexible board layout options.

LED Driver IC Replacement Considerations

MCP1662T-E/OT serves as a direct pin-compatible alternative in SOT-23 packaging. Both variants share identical electrical specifications and functionality. Verify package dimensions and thermal dissipation requirements when substituting between TDFN-8 and SOT-23 form factors.
