Product Details

The DC2969A circuit board enables evaluation of the LTC4372 and LTC4373 low quiescent current ideal diode controllers. The DC2969A-A option is assembled with the LTC4372 controller, whereas DC2969A-B is assembled with the LTC4373 controller. DC2969A includes two independent ideal diode circuits sharing a common ground, operating over a 2.5V to 33V range, and protecting the load against reverse inputs of up to –28V. One of these circuits includes a high side load switch in series with the ideal diode allowing load on/off control with the SHDN/UV jumper. In addition, input dropouts are blocked from the output, permitting capacitors to hold up the load when input power fails. Each channel can carry up to 20A.
