XC9501B091AR-G

DC DC Switching Controllers Overview

The XC9501B091AR-G is a dual-channel step-up DC/DC controller IC from Torex Semiconductor, designed for boost regulator applications. It operates within an input voltage range of 2 V to 10 V and delivers up to 500 mA output current per channel. The device features a fixed switching frequency of 180 kHz and supports adjustable output voltages between 900 mV and 10 V. With a maximum duty cycle of 88% and low quiescent current of 90 uA, it ensures efficient power management in non-isolated topologies. The component is housed in a compact MSOP-10 package and functions reliably across temperatures from -40°C to +85°C.

DC DC Switching Controllers Feature Summary

• Dual-channel architecture enabling independent control of two separate step-up converters
• Low quiescent current consumption for enhanced energy efficiency in battery-powered systems
• Fixed 180 kHz switching frequency allows for the use of small external passive components
• Adjustable output voltage range provides flexibility for various load requirements

DC DC Switching Controllers Applications

• Portable electronic devices requiring multiple regulated voltage rails
• Battery-powered equipment needing efficient step-up conversion
• Embedded systems with limited space for power management components
• Industrial control modules operating in wide temperature environments

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'AR-G' against official Torex documentation to confirm pinout and thermal characteristics. Ensure compatibility with required PCB footprint for MSOP-10 packaging. Confirm that the 180 kHz switching frequency aligns with electromagnetic interference constraints in the target design. Validate input voltage ranges match the system's power source specifications before integration.

DC DC Switching Controllers Selection Notes

Select this component when dual isolated or non-isolated boost outputs are required from a single controller. Consider the 500 mA current limit per channel against peak load demands. Evaluate the MSOP-10 package size against available board real estate. Compare the 90 uA quiescent current against other controllers if ultra-low standby power is critical for the application lifecycle.

DC DC Switching Controllers Part Context

This part belongs to the XC9501 series of dual-channel DC/DC controllers from Torex Semiconductor. The series focuses on high-efficiency power management for portable electronics. The XC9501B091AR-G specifically utilizes a boost topology suitable for stepping up lower battery voltages to higher levels required by system loads.

DC DC Switching Controllers Replacement Considerations

Check for XC9501B092AR-G as a potential variant within the same family, noting differences in internal reference or configuration if documented. Verify pin-to-pin compatibility with other dual-channel boost controllers from different manufacturers only if electrical parameters and package dimensions match exactly.
