Automotive-grade 600 mA buck at 2.25 MHz
It delivers up to 600 mA output from a 2 V to 6 V input rail, switching at 2.25 MHz to keep the external inductor and capacitor small enough for space-constrained ECU layouts.
2.25 MHz switching — inductor and capacitor sizing
At 2.25 MHz the converter can use a 2.2 µH to 4.7 µH inductor and a 10 µF output capacitor, saving board area versus a 500 kHz part that would need 10 µH and 22 µF. The adjustable output down to 0.6 V lets it power 1.8 V and 3.3 V sensor rails from the same BOM.
