Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix YFFR against the manufacturer's official datasheet to confirm the fixed 1.8V output configuration and tape-and-reel packaging format. Ensure compatibility with the target PCB footprint for the DSBGA-6 package. Cross-reference thermal performance data with system-level heat dissipation requirements before finalizing procurement decisions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.8V output is required without external feedback resistor networks. The 600 mA current rating suits moderate-load applications where high efficiency is critical. Consider the 6 MHz switching frequency for smaller passive components compared to lower-frequency alternatives. Verify that the 2.3 V minimum input voltage aligns with the source supply characteristics.
