This means TI will continue to support existing designs for a period, but the part should not be selected for new projects. For ongoing production, confirm the last-time-buy window and evaluate a pin-compatible successor within the same family.
60V input, 3.5A output — industrial and automotive power rail fit
With a 4.5V to 60V input range and 3.5A continuous output, this buck regulator suits 12V, 24V, and 48V industrial buses as well as automotive systems that must survive load-dump transients up to 60V. The adjustable output from 0.8V to 58.8V covers common logic and analog rails.
Switching frequency flexibility
Lower frequencies maximize efficiency at heavy loads; higher frequencies shrink the inductor and output capacitor footprint. The wide range lets the designer trade off efficiency against board area without changing the regulator IC.
Thermal performance with PowerPad package
The 8-PowerSOIC package includes an exposed thermal pad (PowerPad) on the underside. Without adequate thermal management, the device will current-limit or shut down under sustained load.
Split-rail topology for negative output voltages
The TPS54360DDA supports a split-rail buck topology, which allows generation of a negative output voltage from a positive input rail. This is useful for bipolar analog supplies or bias voltages in industrial sensor interfaces. The datasheet application section details the component values for the inverting configuration.
