It operates within an input voltage range of 0.9V to 10V and provides a fixed output voltage of 3.5V. The device supports a maximum output current of 300mA and functions at a switching frequency of 100kHz. It features low quiescent current consumption and includes an enable control feature for power optimization. The component is housed in a compact SC-74A (SOT-753) surface-mount package and is rated for operation between -40°C and +85°C.

Feature Summary

• Integrated step-up topology for boosting low input voltages to stable output levels
• Built-in enable control function for precise power management and system sleep modes
• Compact surface-mount packaging suitable for space-constrained circuit board designs

Applications

• Portable electronic devices requiring efficient battery voltage boosting
• Battery-powered systems with single-cell lithium-ion or alkaline power sources
• Embedded circuits needing stable 3.5V supply from variable input ranges

Procurement Notes

Verify the specific suffix K2UT2U against official ABLIC documentation to confirm pinout compatibility and thermal characteristics. Ensure ordering quantities align with manufacturer standard reel sizes. Cross-reference RoHS compliance status with current regulatory requirements before finalizing procurement specifications.

Selection Notes

Select this component when a fixed 3.5V output is required from inputs as low as 0.9V. The 300mA current capability suits moderate load applications. Consider the 100kHz switching frequency for EMI constraints and external component sizing. The SC-74A package offers a balance between thermal performance and footprint efficiency compared to larger alternatives.

Part Context

This part belongs to the S-8352 series of step-up switching regulators from ABLIC. The series focuses on low-power applications with high efficiency and small form factors. Variants within the series typically differ by output voltage settings and package types, sharing common internal control logic and protection features.

Replacement Considerations

Direct substitutes must match the 3.5V output, 300mA current rating, and SOT-753 package. Verify equivalent switching frequency and quiescent current specifications to ensure circuit stability.
