XC9504B095AR-G

Overview

The XC9504B095AR-G is a dual-channel switching controller IC from Torex Semiconductor, designed for step-down and inverting DC/DC converter applications. It operates within an input voltage range of 2 V to 10 V with a quiescent current of 90 uA. The device supports a fixed switching frequency of 180 kHz and delivers up to 20 mA output current per channel. Output voltages are adjustable from 900 mV to 10 V, with a maximum duty cycle of 87%. It functions in non-isolated boost topology configurations and operates reliably between -40°C and +85°C. The component is housed in a compact MSOP-10 surface-mount package.

Feature Summary

• Dual-channel architecture supporting independent step-down or inverting DC/DC control
• Low power consumption with 90 uA operating supply current
• Adjustable output voltage range spanning 900 mV to 10 V
• Fixed 180 kHz switching frequency for stable regulation

Applications

• Portable battery-powered devices requiring efficient voltage conversion
• Embedded systems needing multiple regulated voltage rails
• Industrial control modules utilizing low-power DC/DC topologies

Procurement Notes

Verify the specific suffix AR-G against official Torex documentation to confirm the MSOP-10 package variant. Ensure compatibility with required thermal management for the SMD/SMT installation style. Confirm that the 180 kHz switching frequency aligns with your system's electromagnetic interference constraints. Validate that the 20 mA output current meets the load requirements for both channels simultaneously.

Selection Notes

Select this component when dual isolated or non-isolated outputs are required from a single input source. The MSOP-10 package offers space efficiency for dense PCB layouts. Consider the 900 mV minimum output voltage limit when designing low-voltage rails. The fixed 180 kHz frequency simplifies external component selection compared to variable frequency controllers.

Part Context

This part belongs to the XC9504 series of dual-channel switching controllers by Torex Semiconductor. The series provides flexible power management solutions for portable electronics. Variants within the series differ primarily by package type and specific electrical tolerances. The XC9504B095AR-G specifically denotes the MSOP-10 package version optimized for surface mount assembly.

Replacement Considerations

XC9504B092AR-G shares identical electrical specifications but utilizes an MSOP-10 package. XC9504B092DR-G offers the same performance in a USP-10 package. Verify pinout compatibility before substituting different package variants.
