Description
This step-up/step-down voltage regulator consists of an isolated DC-to-DC power module between an input step-down (buck) regulator and an output step-up (boost) regulator. This enables up to 100 mA at 12 V out or 300 mA at 5 V out from a wide 5.5 V to 36 V input. * Max current per channel when the other channel current is zero.
