S-8352C30UA-K6PT2U

Overview

The S-8352C30UA-K6PT2U is a step-up switching regulator IC manufactured by ABLIC Inc. It operates with an input voltage range of 0.9V to 10V and provides a fixed output voltage of 3.0V. The device supports a maximum switch current of 282mA and functions at a switching frequency of 250kHz. It utilizes PWM control for efficient power management. The component is housed in a compact SC-74A (SOT-753) surface-mount package, suitable for space-constrained designs. It is rated for operation within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a boost converter topology with internal switching elements for efficient voltage elevation.
• Employs Pulse Width Modulation (PWM) control to maintain stable output regulation under varying load conditions.
• Features a low minimum operating input voltage to maximize battery utilization in portable applications.

Applications

• Battery-powered portable electronic devices requiring voltage step-up
• General-purpose DC-DC conversion in consumer electronics
• Power supply stages for sensor modules and microcontrollers

Procurement Notes

Verify the specific suffix codes against official ABLIC documentation to ensure correct output voltage and package configuration. Confirm RoHS compliance status and environmental declarations prior to integration. Cross-reference the manufacturer part number with distributor databases to validate availability and standard packaging quantities. Ensure design compatibility with required thermal dissipation characteristics for the selected enclosure.

Selection Notes

Select this component when a fixed 3.0V output is required from a single-cell lithium-ion or alkaline battery source. The 282mA output current capability suits moderate load applications. Consider the 250kHz switching frequency for balancing electromagnetic interference and external component size. Verify that the SC-74A package dimensions fit the printed circuit board layout constraints.

Part Context

This part belongs to the S-8352 series of step-up switching regulators from ABLIC. The series is designed for low-power applications requiring efficient voltage boosting from low input sources. The S-8352 models typically integrate the power switch and control logic into a single small-footprint package, simplifying design implementation compared to discrete solutions.

Replacement Considerations

Direct substitutes include other ABLIC S-8352 variants with matching output voltages and packages, such as S-8352C30UA-K6MT2U. External alternatives require matching boost topology, 3.0V output, >282mA current capacity, and SOT-753 packaging. Verify pinout compatibility and control interface similarities before substitution.
