Product details

60V input, 3.5A output — where this buck lives

The Texas Instruments TPS54360BDDAR is a step-down (buck) regulator in the Eco-Mode™ series, designed for applications where the input rail can swing from 4.5V up to 60V.

Switching frequency — sizing the inductor and filter

Running at the lower end cuts switching losses and improves efficiency at heavy loads, but requires a larger inductor and output capacitor. At 2.5MHz the external passives shrink, but the higher switching loss and tighter layout constraints become the trade-off. The non-synchronous topology (no internal synchronous rectifier) means an external Schottky catch diode is needed — factor that into the BOM count.

150°C junction rating — thermal headroom for tight enclosures

That 150°C ceiling is the key spec for designs that run in engine compartments, outdoor telecom cabinets, or industrial motor drives where ambient heat pushes the internal board temperature.

Frequently asked questions

Are TPS54360BDDAR and TPS54360DDA pin-to-pin compatible?

Yes. The TPS54360BDDAR and TPS54360DDA share the same base product number TPS54360, the same 8-PowerSOIC package, and the same pinout. The only difference is the reel quantity suffix — the BDDAR variant ships in Tape & Reel, while the DDA variant ships in tubes. They are functionally identical and can be used interchangeably on the same PCB footprint.

Does TPS54360BDDAR require external compensation?

Yes. The TPS54360BDDAR uses an external compensation network (typically a resistor and capacitor from the COMP pin to ground) to set the control-loop bandwidth and phase margin. The datasheet provides guidelines for selecting these components based on the output capacitor and inductor values.
