XC9503B095AR-G

DC DC Switching Controllers Overview

The XC9503B095AR-G is a dual-channel step-down DC/DC switching controller IC manufactured by Torex Semiconductor Ltd. It operates with a fixed switching frequency of 300kHz and supports a maximum duty cycle of 100%. The device accepts a supply voltage range of 2V to 10V and provides two positive output channels. Designed for surface-mount installation, it utilizes a 10-MSOP package (10-TFSOP). The component functions within an ambient temperature range of -40°C to +85°C and features PWM signal outputs with enable control characteristics.

DC DC Switching Controllers Feature Summary

• Dual-channel buck topology for independent voltage regulation
• Fixed 300kHz switching frequency for consistent noise performance
• 100% maximum duty cycle capability for low dropout operation
• Enable pin functionality for system power management

DC DC Switching Controllers Applications

• Multi-rail power distribution in portable electronic devices
• Voltage regulation for embedded systems requiring multiple rails
• Industrial equipment power supplies with dual output requirements
• Battery-powered applications needing efficient step-down conversion

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'G' indicates RoHS compliance and halogen-free status as per manufacturer standards. Confirm the 10-MSOP package dimensions match the target PCB footprint. Ensure the 2V to 10V input range aligns with the system's supply voltage. Check for any specific ordering codes or distributor-specific part numbers that may differ from the base model number.

DC DC Switching Controllers Selection Notes

Select this component when a dual-output buck controller is required without integrated power switches. The 300kHz frequency offers a balance between efficiency and external component size. Consider the 10-MSOP package constraints for thermal management and board space. Verify that the external MOSFETs selected can handle the required current and voltage levels for the specific application load.
