Description
Demonstration Circuit 2215A, features the LTC®3126, asynchronous buck converter with an integrated losslessinput PowerPath™. Pin selectable (JP2) ideal diode-ORand priority input modes, with programmable undervoltagelockout thresholds provide control over the transitionbetween input sources. The unique all N-channelarchitecture provides efficient operation from either oftwo input sources to a programmable output voltage.In this application the valid input voltage range is setto be from 4.3V to 42V on VIN1 and from 6V to 8.4V onVIN2 providing flexibility and voltage margin for a varietyof applications and power sources. VIN2 can operate to42V. Other input voltage ranges are possible by adjustingVSET1/2 accordingly.
