With a TO-220-compatible footprint, Tech9’s 1 amp/24 VA buck-boost DC to DC power converter can be mounted vertical or horizontally on a circuit board. The units accept input ranging from 6 to 70 V while output remains constant (extended input range down to 4 V is available). Models can be ordered with 3, 5, 9, 12, 15, 24, or 48 VDC output.Inherent high efficiency (cool running) eliminates the heat sink. The converters measure just 1 in. W x 1 in. H x 0.55 in. T and offer ±2% output voltage tolerance with excellent line and load rejection characteristics (60 DB typical). The units are short circuit proof and can be operated in ambient temperatures as high as 85°C.
