DC1624A-A

DC1624A-A demonstration circuit contains two independent rail circuits each with Hot Swap™ and ideal diode functionality provided by the LTC4225-1 dual ideal diode and Hot Swap controller. DC1624A facilitates evaluation of LTC4225 performance in different operation modes such as supply ramp-up, power supply switchover, steady state, and overcurrent faults. Power supply switchover mode can be realized as either an ideal diode functionality or as a prioritize functionality. Each DC1624A rail circuit is assembled to operate with a 12V supply and 11.5A maximum current load. The board has LTC4225 controller, 2x MOSFETs operating as ideal diodes, 2x MOSFETs operating as Hot Swap devices, 2x power sense resistors, 2x jumpers for independently enabling each rail, 4x LEDs to indicate power good and fault conditions separately for each channel and input voltage snubbers. There are pads for optional RC circuits for each Hot Swap MOSFET gate in order to adjust output voltage slew rate.

• Board also has pads for alternative config with hot swap MOSFET located ahead of ideal diode MOSFET
