Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix (e.g., /NOPB) against the manufacturer's datasheet to confirm lead-free compliance and exact pinout configuration. Ensure the WSON-8 package variant matches the PCB footprint requirements. Cross-reference the part number with official distributor catalogs to validate current production status and availability before finalizing procurement plans.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing circuits requiring high input voltage tolerance up to 75 V. The constant on-time topology simplifies compensation compared to fixed-frequency PWM controllers. Consider the 500 mA output capability and the need for external inductor selection based on the desired ripple current and switching frequency settings.
