Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation as TAEJIN Technology Co. against standard Texas Instruments datasheets, as this part number follows TI naming conventions but may be sourced from alternative manufacturers. Confirm the package type corresponds to the 'R' suffix specification. Ensure compatibility with the required 52kHz switching frequency and inductor selection guidelines provided in the specific product documentation.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12V output at 1A is required from a higher input voltage rail. The wide input voltage range accommodates varying source conditions. Consider the 52kHz switching frequency for inductor size trade-offs. Verify that the thermal performance meets the application's ambient temperature requirements given the fixed topology and current rating.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM2575 family of simple step-down switching regulators. The 'HV' variant typically supports higher input voltages compared to standard versions. The '12' suffix indicates the fixed 12V output version. The 'R' suffix usually denotes a surface-mount package option, distinguishing it from through-hole variants like the TV series.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include LM2575HVS-12 or LM2575HVM-12 from Texas Instruments. Alternative sources such as onsemi or HGSEMI offer pin-compatible equivalents. Verify that replacement parts maintain the 12V fixed output and 1A current capability.
