Because the BD90610EFJ-CE2 uses an external Schottky catch diode rather than a synchronous FET, the total efficiency depends on the diode forward voltage and the switching frequency trade-off; at 500 kHz the diode conduction losses dominate at light load. The adjustable output uses an external resistor divider from the FB pin; the 0.8 V reference sets the minimum output, and the maximum output equals the input voltage minus the dropout of the internal switch.","metaTitle":"ROHM BD90610EFJ-CE2 Buck Regulator, 1.25 A, AEC-Q100","metaDescription":"ROHM BD90610EFJ-CE2 step-down buck regulator, 1.25 A output, 5-36 V input, adjustable, AEC-Q100, -40 to +125°C.
