Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the specific suffix 'PT' corresponds to the tube packaging format rather than tape and reel, as this affects handling procedures. Confirm the exact thermal pad requirements for the PowerTSSOP-16 package during layout design. Ensure compatibility with the intended switching frequency settings regarding external component selection. Cross-reference the datasheet revision date to confirm feature consistency before finalizing the bill of materials.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a 1 A buck converter solution is required with an input voltage up to 36 V. The adjustable frequency feature enables trade-offs between efficiency and passive component size. Consider the 16-PowerTSSOP package for applications requiring moderate thermal dissipation without excessive board space consumption. Verify that the 1 V minimum output requirement aligns with the target load specifications.

Voltage Regulators - DC DC Switching Regulators Part Context
