This step-up voltage regulator consists of a pair of isolated DC-to-DC power modules in front of a step-up (boost) regulator. This enables up to 125 mA continuous at 12 V out from a 5 V input with full galvanic isolation between the input and output. The 5 V output of one isolation IC and the 10 V output of the pair of isolation ICs in series are also available.

Input voltage Output voltages Max continuous output current Size
4.5 V to 5.5 V 12 V 125 mA* 0.45″ × 1.0″
10 V 175 mA*
5 V 300 mA*

* Max current per channel when the other channel currents are zero.

Alternatives available with variations in these parameter(s): output voltage Select variant…
