DC2315A-B

DC2315A-B demonstration circuit is intended to demonstrate the performance of the LTC4235-2 dual 12V ideal diode-OR and Single Hot Swap™ controller with current monitor. The controller enables monitoring of the load current by providing a signal that is 100x the sense resistor voltage. The DC2315A allows verification of the LTC4235 Hot Swap and ideal diode functionality during individual rail ramp-up and ramp-down events, during power supply switchover, in steady state, and in overcurrent fault conditions. The main board components are the LTC4235 controller, two power MOSFETs functioning as ideal diodes and one power MOSFET controlled as a Hot Swap switch, two jumpers for enabling the second ideal diode and Hot Swap (ON-SEL), two LEDs to indicate power good and fault conditions, seven banana jacks for connecting power supplies and load, and many turrets and pads for observing circuit signals.

• Input supply range from 9V to 14V
• Board current limit of 9A(typ) (OUT = 11V)
• Provides automatic retry after a fault
