S-8333TCIB-T8T1U

Overview

The S-8333TCIB-T8T1U is a boost switching voltage regulator manufactured by ABLIC Inc. It operates with an input voltage range of 1.8 V to 6 V and provides a fixed output voltage of 9.2 V. The device supports an output current of 160 mA and features a switch frequency adjustable between 280 kHz and 1.08 MHz. It consumes 450 µA of operating supply current and functions within a temperature range of -40°C to +85°C. The component is housed in an 8-pin TSSOP package.

Feature Summary

• Boost topology for step-up voltage regulation
• Adjustable switching frequency control
• Low power consumption operation
• Integrated shutdown capability

Applications

• Portable electronic devices requiring voltage boosting
• Battery-powered systems needing stable higher voltage rails
• General purpose DC-DC conversion in compact form factors

Procurement Notes

Verify the specific suffix T8T1U corresponds to the required reel packaging quantity and tape specifications. Confirm that the fixed 9.2 V output aligns with system requirements, as other variants in the S-8333 series offer different voltages. Ensure the TSSOP-8 footprint matches the PCB design. Check for obsolescence notices, as some S-8333 variants are marked as not recommended for new designs.

Selection Notes

Select this part when a boost converter is needed from a 1.8 V to 6 V source. The 160 mA output current limits suitability for high-power loads. The adjustable frequency allows optimization for efficiency or external component size. Compare against buck regulators if input voltage is consistently higher than the required output. Verify thermal performance at maximum load within the specified temperature range.

Part Context

This component belongs to the S-8333 series of switching regulators from ABLIC. The series includes various topologies and output configurations. The S-8333TCIB variant specifically denotes the boost configuration with a 9.2 V fixed output. Other siblings may differ in output voltage, package type, or control interface, requiring careful model number verification during selection.

Replacement Considerations

Direct substitutes include other S-8333 series parts with identical boost topology and similar electrical characteristics, such as S-8333ABCB-T8T1G, provided the output voltage and pinout compatibility are confirmed. Cross-referencing datasheets for pin definitions and thermal resistance is essential before substitution.
