XCM414B103D2-G

Overview

The XCM414B103D2-G is a switching controller voltage regulator with an integrated bridge diode designed for wireless power receivers. It operates within an input voltage range of 2V to 26V and provides a fixed output voltage of 10.3V. The device supports up to 300mA output current and delivers 1.4W of output power. It features a low operating supply current of 5µA and functions across a temperature range of -40°C to +85°C. The component utilizes a non-isolated topology and is housed in an 8-PowerXDFN (USP-8B10) surface-mount package.

Feature Summary

• Integrates a synchronous rectifier bridge diode to eliminate external components
• Optimized for high-efficiency AC/DC conversion in wireless power applications
• Supports wide input voltage ranges suitable for resonant receiver circuits

Applications

• Wireless power receiver modules
• AC/DC converters for portable devices
• Battery charging systems in wireless environments

Procurement Notes

Verify the specific suffix D2-G against the manufacturer datasheet to confirm the exact output voltage rating of 10.3V, as variations exist within the XCM414 series. Ensure compatibility with the target wireless power transmission frequency and coil configuration. Confirm that the USP-8B10 package footprint aligns with the PCB design requirements for thermal dissipation and mechanical stability.

Selection Notes

Select this component when a compact solution for wireless power reception is required without external rectifiers. The fixed 10.3V output suits specific battery chemistries or load requirements. Consider the 5µA quiescent current for standby efficiency needs. Validate that the 2V minimum input voltage meets the rectified coil voltage under light load conditions.

Part Context

This part belongs to the XCM414 series from Torex Semiconductor, specialized for wireless power transfer systems. The series integrates power management functions to reduce board space. The B103 designation indicates the specific 10.3V output variant within the family, distinguishing it from other voltage options like 5V or 10.1V.

Replacement Considerations

Direct substitutes include other XCM414 variants such as XCM414B101D2-G for 10.1V output or XCM414B050D2-G for 5V output, provided the system voltage requirement is adjusted accordingly. Cross-model comparison is necessary to ensure pinout and thermal characteristics remain compatible.
