Functional alternative in the same package with matching voltage/current ratings but a different switching frequency (150kHz).
Finding a substitute for the LM2576HVS-5.0(UMW) 3A, 60V buck regulator requires careful attention to input voltage and switching frequency. While several parts offer similar output, few match the high-voltage capability without other trade-offs.
Mismatched max input voltage or switching frequency requires careful review.
Most candidates use a compatible TO-263 style package, but verification is advised.
No direct drop-in replacement exists. All candidates have critical differences in either input voltage or switching frequency.
If Vin < 40V, use LM2576S-5.0. If Vin > 40V, use LM2596HVS-5.0 but redesign passives for 150kHz operation.
The primary risk is substituting with a standard 40V regulator in a system designed for the target's 60V input, leading to device failure.

The best alternative depends on your design. For applications under 40V, LM2576S-5.0 is a strong choice. For higher voltage, LM2596HVS-5.0 is an option if you can adjust external components for its different switching frequency.
