Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'TLX' against the manufacturer's official datasheet to confirm pinout and marking details. Ensure the order includes the '/NOPB' designation if lead-free compliance is required. Cross-reference the package type DSBGA-12 with your PCB footprint library before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution is needed for high-voltage step-down applications requiring moderate current. The 2.6 MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Verify that the 600 mA output current meets the load requirements and that the input voltage does not exceed the absolute maximum rating.
