The TPS54360BQDDARQ1: Maximum input is 60 V, minimum 4.5 V. Output is adjustable from 0.8 V up to 58.8 V.
Lower frequencies reduce switching losses and improve efficiency at heavy loads; higher frequencies allow smaller inductors and faster transient response. The Eco-Mode™ pulse-skipping feature maintains light-load efficiency by reducing switching activity at low output currents.
The TPS54360BQDDARQ1 is the automotive AEC-Q100 qualified version of the base TPS54360. The base TPS54360 is pin-compatible and functionally identical but lacks the extended temperature range and automotive qualification. For a direct replacement in automotive designs, the BQDDARQ1 suffix is the correct choice.
