Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix YZDT corresponds to the 8-DSBGA package variant during procurement. Confirm that the ordering part number matches the required tape-and-reel quantity specified in the manufacturer's packaging data. Ensure compatibility with the target PCB land pattern dimensions for the 1x1.5 mm package.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when board area is constrained and a fixed 3-MHz frequency is acceptable. It is appropriate for designs requiring moderate output currents up to 500 mA without the need for adjustable feedback networks. Consider alternative models if higher current capacity or programmable switching frequencies are required.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the TPS623xx family of ultra-small step-down converters from Texas Instruments. The family shares common architectural features including synchronous rectification and fixed-frequency operation. Variants within the series differ primarily in package types, maximum current ratings, and switching frequency options to suit diverse form factor requirements.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Compatible substitutes include TPS62302DRCR and TPS62302YZDR. Verify pinout compatibility and package dimensions before substitution. Ensure electrical parameters such as switching frequency and output current limits meet the original design specifications.
