DC1635A

DC1635A is a LTC4412/LTC4414: dual low loss high voltage PowerPath controllers demonstration board. Demonstration circuit 1635A features the LTC®4412HVIS6 and LTC4414EMS8, low loss PowerPath™ controllers. Each controller is capable of automatically switching between primary and auxiliary power sources for a single output. There are two electrically isolated circuits, one for each IC, for independent evaluation. The LTC4412 circuit is intended for lower current loads while the LTC4414 circuit is capable of driving larger PMOS devices for higher current loads. The input supply voltage ranges are from 2.5V to 36V for LTC4412 and 5V to 36V for LTC4414. As initially configured with the default MOSFET, the LTC4412 circuit maximum input voltage is 18V. The LTC4412 and LTC4414 circuit current limits are 2A and 8A respectively.
