Description
The Bel S7BC-10E2Ax is part of the non-isolated DC/ DC power converter series. The modules use a SMT package. These converters are available in a range of output voltages from 0.75V to 3.63V over a wide range of input voltage (Vin = 4.5V-14V). The Bel S7BC-10E2Ax has a sequencing feature that enables designers to implement various types of output voltage sequencing w hen powering. The efficiency is typically 93% at 3.3V output at 12V input at full load. Part Selection Output Voltage Input Voltage Max. Output Current Max.
