Overview
The XC9505B093DR-G is a dual-channel DC/DC controller IC manufactured by Torex Semiconductor. It supports both step-down (buck) and inverting topologies within a single device. The component operates with an input voltage range of 2.7V to 5.5V. It integrates synchronous rectification for improved efficiency. The unit is housed in a compact USP-10B package. Factory packaging quantity is 3000 units per reel.
Feature Summary
- Dual-channel architecture supporting independent buck and inverting configurations
- Integrated synchronous rectification technology for enhanced power conversion efficiency
- Compact surface-mount packaging suitable for space-constrained designs
Applications
- Portable electronic devices requiring multiple voltage rails
- Battery-powered systems utilizing step-down and negative voltage generation
- Embedded systems needing integrated power management solutions
Procurement Notes
Verify the specific suffix 'G' indicates RoHS compliance status according to the manufacturer's current documentation. Confirm the USP-10B package dimensions match your PCB footprint requirements. Ensure the ordering quantity aligns with the standard factory reel size of 3000 units. Cross-reference the datasheet revision date to confirm pinout compatibility with existing designs.
Selection Notes
Select this component when a design requires both positive regulated output and a negative rail from a single low-voltage source. The dual-channel capability reduces component count compared to using separate controllers. Verify that the required output currents fall within the specified limits for each channel. Consider the thermal performance of the USP-10B package under maximum load conditions.
Part Context
This part belongs to the XC9505 series of dual-channel DC/DC controllers. The series is designed for applications requiring flexible power topology options. Similar parts in the lineup may offer different input voltage ranges or output configurations. The XC9505 family emphasizes high efficiency through synchronous rectification techniques.
Replacement Considerations
Direct substitutes include other XC9505 variants with different output voltage settings or package options. Verify electrical parameters such as switching frequency and quiescent current when considering alternative models. Ensure the replacement maintains the same dual-channel functionality and package footprint.
