SC600DIMSTRT

Overview

The SC600DIMSTRT is a single-output LED driver IC from Semtech, utilizing a switched capacitor (charge pump) topology. It operates within an input voltage range of 2.5 V to 6.5 V and delivers a maximum output current of 120 mA at an output voltage of 5 V. The device functions at a switching frequency of 650 kHz and is housed in a 10-MSOP surface-mount package. It supports constant current regulation for LED backlighting applications across an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates a charge pump topology for efficient DC-DC regulation in battery-powered systems
• Provides precise constant current control for LED backlighting stability
• Supports wide input voltage compatibility with lithium-ion power sources

Applications

• LED backlighting for portable electronic devices
• Battery-operated power supply applications
• High-efficiency LED driver circuits requiring compact form factors

Procurement Notes

Verify component authenticity through authorized Semtech distributors or certified partners. Confirm the specific suffix STRT indicates tape-and-reel packaging configuration. Ensure compliance with RoHS directives as specified in official documentation. Cross-reference part numbers carefully to distinguish between similar variants such as SC600CIMLTRT which may have different electrical characteristics.

Selection Notes

Select this component when designing circuits requiring a single-channel constant current source with charge pump architecture. It is suitable for applications needing input voltages between 2.5 V and 6.5 V. Consider the 10-MSOP package constraints for PCB layout. Verify that the 120 mA output current meets the specific LED string requirements without exceeding thermal limits.

Part Context

This part belongs to the SC600 series of versatile charge pump drivers designed by Semtech Corporation. The series targets battery-operated applications where high efficiency and small footprint are critical. The SC600DIMSTRT variant specifically offers regulated output capabilities compared to basic regulator versions, enhancing performance in sensitive backlighting environments.

Replacement Considerations

Direct substitutes include other SC600 series variants like SC600CIMLTRT, though electrical parameters such as output current may differ. Verify pin compatibility and functional equivalence before substitution. No alternative part numbers are explicitly confirmed as direct replacements in public documentation.
