Linear Technology DC2423A Demo Manual

Anyside™ High Voltage Isolated Switch Controller
DESCRIPTION
Demonstration circuit 2423A showcases the
Isolated Switch Controller in either a typical 48V applica-
tion (–A) or in a high voltage 380V application (–B). The
board may be configured for either high side or low side
operation, dependent on the connection of external sup-
ply 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
