Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'DPR-G' against official Torex documentation to confirm RoHS compliance and tape-and-reel specifications. Ensure that the required output voltage matches the fixed 2.4 V configuration, as this variant does not support adjustable outputs. Cross-reference the SOT-89-5 footprint dimensions with your PCB design guidelines prior to procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed 2.4 V output is required from a 2.5 V to 5.5 V input source. It is suitable for designs prioritizing high peak current capability up to 1.5 A. Consider the 1.2 MHz switching frequency for balancing EMI performance and passive component size. Verify thermal dissipation capabilities within the SOT-89-5 package for the intended load profile.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the XC9288 series of synchronous step-down DC/DC converters. The series is characterized by its integrated control IC and driver FETs, designed for space-constrained applications. The B-series designation typically indicates specific internal configurations or feature sets within the broader XC9288 family, distinguished from other variants like the A-series.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other XC9288 series variants with compatible output voltages, such as XC9288B2ADPR-G (2.05 V) or XC9288B36DPR-G (3.6 V), provided the system voltage requirement allows adjustment. Ensure pinout compatibility and thermal characteristics match the existing design constraints.
