DC2423A-B

DC2423A-B is a demonstration circuit 2423A that shows the LTM9100 isolated switch controller in a high voltage 380V application. The board may be configured for either high side or low side operation, depending on the connection of external supply and load to the banana jacks. An on-board capacitive load may also be wired into the circuit. LEDs indicate the presence of input and output voltage. The MOSFET can be easily exchanged or replaced due to screw terminal block mounting. Protection is also included to protect the GATE and SENSE pins in the event of MOSFET destruction. The circuit can be operated manually or by computer control.
