XC9237B2ADER-G

Voltage Regulators - DC DC Switching Regulators Overview

The XC9237B2ADER-G is a synchronous step-down DC/DC converter from Torex Semiconductor. It features HiSAT-COT control for stable operation with low-ESR ceramic capacitors. The device supports an input voltage range of 2.5V to 5.5V and delivers up to 1.5A output current. It includes a fixed 2.05V output voltage option, 3MHz switching frequency, and ultra-low quiescent current of 15uA. Integrated protections include overcurrent, thermal shutdown, and soft-start functionality.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• HiSAT-COT control architecture ensures stability with small ceramic output capacitors
• Ultra-low quiescent current minimizes power loss in standby modes
• Integrated protection mechanisms safeguard against overload and overheating

Voltage Regulators - DC DC Switching Regulators Applications

• Portable electronic devices requiring efficient power management

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'B2' confirms the 2.05V fixed output configuration before procurement. Ensure compatibility with the USP-C-EP-6 package footprint during PCB layout. Confirm RoHS compliance status through official documentation. Cross-reference pin assignments with the manufacturer datasheet to prevent integration errors.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this model for applications requiring high efficiency at light loads due to its low quiescent current. The fixed 2.05V output suits digital logic supplies directly. Consider the 3MHz frequency for smaller external component sizes. Evaluate thermal performance given the compact package size under maximum load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the XC9237 series of synchronous buck converters. It shares architectural similarities with the XC9287 series but offers different current capabilities. The B2 suffix denotes a specific fixed output voltage variant within the product family. It complements other Torex PMIC solutions for complete system power management.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include XC9287B2ADER-G for higher current requirements. XC9237B3ADER-G serves as an alternative for different fixed voltage outputs. Verify pin-to-pin compatibility and thermal characteristics when considering cross-series replacements.
