These converters are available in a range of output voltages from 1.0 Vdc to 3.3 Vdc. It is packaged in a compact, overmolded package rated at 12 A. The output is closely regulated and the efficiency of 3.3 Vdc output module 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.
