IS32SE5117B-QWLCA3-TR

Overview

The IS32SE5117B-QWLCA3-TR is a synchronous step-down DC/DC converter manufactured by Lumissil Microsystems. It integrates high-side and low-side power MOSFETs to deliver efficient voltage regulation for portable electronic devices. The device operates with an input voltage range of 2.5V to 5.5V and provides a programmable output voltage from 0.6V to 3.3V. It supports switching frequencies up to 2.2MHz, enabling the use of compact external components. The IC features adjustable current limit protection and thermal shutdown mechanisms to ensure reliable operation under varying load conditions.

Feature Summary

Integrated synchronous rectification architecture for enhanced efficiency
Programmable switching frequency to optimize component size
Built-in over-current and thermal protection circuits

Applications

Portable consumer electronics
Battery-powered handheld devices
Embedded systems requiring stable low-voltage rails

Procurement Notes

Verify the specific suffix QWLCA3-TR against official Lumissil documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with required operating temperature ranges and check for any recent lifecycle status updates directly from the manufacturer before procurement.

Selection Notes

Select this component when a compact solution is needed for converting 3.7V lithium-ion battery voltages to lower logic levels. Consider the maximum output current capability and the desired switching frequency trade-off between efficiency and passive component size during the design phase.

Part Context

This part belongs to the IS32SE series of synchronous buck converters. It is designed as a cost-effective alternative to discrete solutions, offering high integration in a small footprint suitable for space-constrained mobile applications.

Replacement Considerations

Check for direct pin-to-pin compatible alternatives within the same family or from other manufacturers that match the input/output voltage ranges and current capabilities. Verify equivalent switching frequency and control interface compatibility.
