Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify availability status as Mouser indicates limited supply or special order requirements for this part number. Confirm RoHS compliance details via the official datasheet before procurement. Ensure the TO-220-7 through-hole package matches your PCB layout constraints. Cross-reference the specific HV suffix requirements against your system's input voltage headroom needs.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a high input voltage capability up to 64 V is required for buck conversion. The integrated power switch simplifies design by reducing external component count compared to discrete solutions. Consider the thermal performance of the TO-220-7 package for heat dissipation at full load. Verify that the 100 kHz switching frequency aligns with your electromagnetic interference (EMI) filtering strategy.
