Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix LGIZ confirms the -40°C to +125°C temperature grade and standard mounting style. Confirm RoHS compliance status via the manufacturer datasheet before integration. Check for REACH SVHC declarations as required by regional regulations. Ensure input voltage specifications align with system transient requirements up to 70V.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this model for applications requiring a fixed 5V output from a 48V bus with up to 10A capacity. Consider the LGA-85 package constraints for PCB layout and thermal management. Evaluate if the 600 kHz switching frequency suits the electromagnetic interference requirements. Compare against other PI354x variants if different output voltages or current ratings are needed.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the Vicor PI354x-00 series of high-voltage ZVS buck regulators. These devices integrate controllers, power switches, and support components into a single SiP. The series is designed for SELV compliant systems with steady-state operation limited to 60V, offering best-in-class power efficiency for point-of-load applications.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations
