Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the complete part number including suffixes against official Texas Instruments documentation to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status through the manufacturer's datasheet or certification documents prior to procurement. Ensure the supplier provides valid traceability records matching the original equipment manufacturer's standards.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a 36V input rail requires conversion to lower voltages with moderate current demands. The 2.1MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Verify that the required output voltage falls within the 1V to 28V adjustable range. Consider the 8-SO-PowerPAD thermal performance for the specific PCB layout environment.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LMR23625 series of synchronous buck converters. It shares architectural similarities with other members of the SIMPLE SWITCHER family designed for 36V input applications. The CDDAR designation specifically indicates the SOIC-8 PowerPAD package variant with reel packaging, distinguishing it from other pin-compatible or functional equivalents in the broader portfolio.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Consult official substitution guides for direct replacements such as LM63625 variants or LMR33620 if current requirements differ. Verify pinout compatibility and thermal characteristics before substituting with non-Texas Instruments components.
