Product details

Automotive buck converter in 8-HTSOP-J

The BD90620EFJ-CE2 is a ROHM Automotive-grade step-down (buck) converter delivering 2.5 A from a 5 V to 36 V input rail.

Switching frequency and thermal design

The switching frequency is programmable from 50 kHz to 500 kHz. A lower frequency reduces switching losses at light load; a higher frequency shrinks the inductor and output capacitor footprint. No synchronous rectifier is integrated — the external Schottky diode selection sets the forward drop and recovery losses. The 2.5 A continuous output rating assumes adequate copper area on the PCB; derate above 85°C ambient per the ROHM application note.
