These converters are available in a range of output voltages from 0.9 Vdc to 2.5 Vdc. It is packaged in a compact, overmolded package rated at 3 A. Optional lead forming provides a vertical mount product for minimal footprint or a surface mount option for a very low profile. The output is closely regulated and the efficiency for 2.5 Vdc output is typically 93% at full load. Typical features include remote on/off, input under voltage lockout, over current protection and short circuit protection. Part Selection Output Voltage Input Voltage Max. Output Current Max.
