Voltage Regulators - DC DC Switching Regulators Procurement Notes
Verify the specific suffix 'T7A' against official Renesas documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with moisture sensitivity levels and reflow soldering profiles defined in the datasheet. Confirm RoHS compliance status through authorized channels prior to integration.
Voltage Regulators - DC DC Switching Regulators Selection Notes
Select this component when designing systems requiring flexible buck-boost topology within a 40 V input limit. The 2.5 A capability suits moderate load applications. Consider the QFN-EP-20 package for thermal performance and board space constraints compared to smaller regulators.
Voltage Regulators - DC DC Switching Regulators Part Context
This part belongs to the ISL85403 family of single-output switching regulators manufactured by Renesas Electronics. It complements other PMIC offerings like the ISL85410 and ISL85413, providing higher current capacity than the 300 mA ISL85413 while maintaining wide input voltage support across automotive and industrial grades.
Voltage Regulators - DC DC Switching Regulators Replacement Considerations
Direct substitutes include the ISL85403FRZ (tray packaging) or the ISL85403FRTZ (tape and reel). Verify pinout and electrical parameters match exactly before substitution.
