600 mA, 2.25 MHz automotive buck — fixed 2.5 V rail
It delivers a fixed 2.5 V output at up to 600 mA from an input range spanning 2 V to 6 V, switching at 2.25 MHz. The 2.25 MHz switching frequency lets the designer use small-value inductors and ceramic output capacitors, shrinking the total solution footprint — a direct trade-off against the slightly higher switching losses compared to a 1 MHz part. The fixed 2.5 V output eliminates the external feedback divider network, saving two resistors and one feedback trace on the PCB. This is a clean drop-in for any 2.5 V rail in an automotive ECU, ADAS sensor module, or infotainment processor core supply.
AEC-Q100 grade and 105°C ceiling — where it fits
It suits engine-control units, body controllers, ADAS camera modules, and infotainment head units — any 2.5 V rail that must survive under-hood thermal cycling without a ceramic capacitor derating headache. The synchronous rectifier improves efficiency at light loads compared to a diode-rectified buck, which matters for always-on automotive modules that spend most of their time in standby.
