XC9505B095AR-G

Overview

The XC9505B095AR-G is a dual-channel DC/DC controller IC from Torex Semiconductor, designed for step-down and inverting topologies. It operates with a standard voltage supply of 0.9V and features a fixed switching frequency of 500kHz. The device supports PWM control and automatic PWM/PFM switching modes to optimize efficiency across varying load conditions. It is housed in a 10-MSOP package and functions within an operating temperature range of -40°C to 85°C.

Feature Summary

• Dual-channel architecture supporting simultaneous step-down and inverting DC/DC conversion
• Automatic switching between PWM and PWM/PFM modes for enhanced light-load efficiency
• Low standard voltage supply requirement of 0.9V for energy-efficient operation

Applications

• Battery-powered portable electronic devices requiring efficient power management
• Industrial equipment utilizing low-voltage logic supplies
• Embedded systems needing isolated or inverted voltage rails alongside main regulation

Procurement Notes

Verify the specific suffix 'G' indicates RoHS compliance as per manufacturer standards. Confirm the package variant matches the 10-MSOP specification required for your PCB footprint. Ensure the input voltage range aligns with your system's 2V to 10V operational limits before finalizing procurement orders.

Selection Notes

Select this component when dual output regulation is required from a single controller unit. It is suitable for applications demanding high efficiency at light loads due to its PFM capability. Consider the 500kHz switching frequency for EMI constraints and external component sizing requirements compared to higher-frequency alternatives.

Part Context

This part belongs to the XC9505 series of PWM-controlled DC/DC controllers. It complements other Torex power management solutions by providing multi-output capabilities in a compact surface-mount package. The series targets applications where space constraints and power efficiency are critical design factors.

Replacement Considerations

Direct substitutes may include other dual-channel DC/DC controllers from Torex with similar pinouts and electrical characteristics. Verify compatibility regarding switching frequency and control interface before substitution.
