Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'PWP' corresponds to the 14-PowerTSSOP surface-mount package configuration. Confirm that the component meets RoHS compliance standards required for your assembly process. Ensure the ordering quantity aligns with manufacturer tape-and-reel specifications to prevent handling issues during placement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when an input voltage up to 18V and a continuous 3A output are required. The integrated power stage eliminates the need for external Schottky diodes. Consider the 700kHz switching frequency for balancing component size and efficiency against noise sensitivity requirements in the target application circuit.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the TPS543xx series of SWIFT converters. It shares architectural similarities with the TPS54329 but differs in input voltage tolerance and package options. The PowerTSSOP package provides improved thermal dissipation compared to standard HTSSOP variants, supporting higher current densities in compact layouts.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct pin-to-pin replacements include the TPS54329PWPR for similar performance with potentially different thermal characteristics. For lower current needs, the TPS54226PWPR serves as a compatible alternative. Verify thermal management requirements when substituting with packages having different thermal pad configurations.
