The QME48T30057 Series is a DC-DC converter in a through-hole quarter-brick, accepting 36 ~ 75 VDC and delivering a regulated 5.7 VDC at 30 A for architectures that require a non-standard intermediate rail voltage. Patented circuit and thermal packaging eliminate the need for a heat sink. Output trim of -20% ~ +10% extends the usable voltage window. Suited to distributed power designs in enterprise networking and telecom equipment.
