The Q48S15050 Series is a 75 W DC-DC converter in a surface-mount quarter-brick, accepting 36 ~ 75 VDC and delivering a regulated 5 VDC at 15 A. At 7.11 mm tall, the low-profile body matches the thermal performance of 20 A quarter-brick designs without a heat sink and avoids disturbing the airflow patterns that protect surrounding components. Suited for dense 5 V logic rails in telecom line cards and networking switching equipment.
