XP Power QSB Series | DigiKey Daily

XP Power QSB series DC-DC converters are high efficiency 150 W converters with a wide 8:1 input range in a standard half brick package. QSB series converters accept inputs from 9 V to 75 V, covering nominal inputs of 12, 24, and 48 V. The converters offer a single regulated output, with voltage options from 12 to 48 V to address common voltage requirements. Outputs can also be trimmed by ±10% to address line losses or to produce non-standard voltages. XP Power QSB series converters also have a control pin that allows for remote on/off control and can be used for power sequencing.
