Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix '6' indicates the fixed frequency variant (600 kHz to 1.3 MHz) distinct from other LM5000 variants. Confirm RoHS compliance status via official documentation. Ensure the WSON-16 package footprint matches the target PCB layout requirements before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed higher switching frequency is required compared to the standard LM5000 models. The choice depends on the need for smaller external passive components due to the elevated frequency range. Verify that the 2 A current limit meets the peak load demands of the specific application circuit design.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM5000 family of high-voltage switching regulators. It shares core architectural similarities with other LM5000 variants but differs in its internal oscillator configuration.
