Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix and manufacturer details against official datasheets before procurement. Confirm that the component meets all required electrical specifications for the target application. Ensure compatibility with existing circuit designs regarding input and output voltage levels. Check for any obsolescence notices or lifecycle status updates from the manufacturer prior to finalizing orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.0 V output is required from a 2.3 V to 5.5 V input source. Consider the 4 MHz switching frequency for minimizing external passive component sizes. Evaluate the 6-DSBGA package constraints for PCB layout and thermal management. Ensure the load current does not exceed the 1 A rating under all operating conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM3691 series of high-accuracy, miniature step-down converters designed for portable applications. It shares the same core architecture and packaging as other variants in the family, differing primarily in the fixed output voltage setting. The series is characterized by its small form factor and efficiency in low-power environments.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM3691TLX-1.2/NOPB offers a similar form factor but provides a 1.2 V output instead of 1.0 V. LM3691TLX-3.3/NOPB is another variant within the same series featuring a 3.3 V fixed output. These parts share identical pinouts and electrical characteristics except for the regulated output voltage level.
