Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'DDCR' corresponds to the SOT-23-THIN-6 package and Reel tape-and-reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the ordering part number matches the required pinout and marking specifications for your PCB layout.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a single-output synchronous buck converter is needed with an input range up to 17 V and 4 A load capability. The D-CAP2™ topology simplifies design by eliminating external error amplifier compensation. Consider the 560 kHz switching frequency for balancing efficiency and passive component size. Verify that the thermal performance in the SOT-23-THIN-6 package meets the application's heat dissipation requirements.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the TPS564201 series of synchronous step-down converters. It is distinct from similar models like the TPS564242, which uses a different package (SOT-563) and higher switching frequency (1.2 MHz). The TPS564201DDCR specifically denotes the thin SOT-23 variant optimized for space-constrained designs.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes may include other members of the TPS5642xx family, such as TPS564242DRLR, provided the package change from SOT-23-THIN-6 to SOT-563 is acceptable. Verify pin compatibility and electrical parameter alignment before substitution.
