XC9504B095DR-G

Overview

The XC9504B095DR-G is a dual-channel step-down and inverting DC/DC controller IC manufactured by Torex Semiconductor. It utilizes a boost topology with a fixed switching frequency of 180 kHz and a maximum duty cycle of 87%. The device supports an output voltage range from 900 mV to 10 V and provides an output current capability of 20 mA. It operates within a temperature range of -40°C to +85°C and is housed in a USP-10 surface-mount package.

Feature Summary

• Dual-channel architecture supporting both step-down and inverting DC/DC conversion topologies
• Integrated switching controller optimized for compact power management designs

Applications

• Portable electronic devices requiring efficient power regulation
• Battery-powered systems utilizing step-down or inverting voltage conversion
• Compact consumer electronics with space-constrained PCB layouts

Procurement Notes

Verify the specific suffix against official Torex Semiconductor documentation to confirm pinout and electrical characteristics, as variations may exist within the XC9504 series. Ensure compatibility with required input voltage ranges and thermal management solutions for the USP-10 package. Cross-reference datasheet revisions to validate performance parameters for your specific application environment.

Selection Notes

Select this component when a dual-output solution combining buck and inverting functions is required in a minimal footprint. The 180 kHz switching frequency offers a balance between efficiency and external component size. Consider the 20 mA output current limit and 10 V maximum output voltage when designing load circuits. Verify that the USP-10 package thermal dissipation meets system requirements under full load conditions.

Part Context

This part belongs to the XC9504 series of dual-channel DC/DC controllers from Torex Semiconductor. The series is designed for applications needing multiple regulated outputs from a single controller unit. The XC9504B095 variant specifically integrates the step-down and inverting capabilities within a small USP-10 package, targeting portable and space-sensitive electronic designs.

Replacement Considerations

Consult Torex Semiconductor official documentation for confirmed substitute part numbers within the XC9504 family. Verify functional equivalence regarding topology, output configuration, and package dimensions before substitution.
