Demonstration Circuit 786 showcases the LTC4260CGN positive high voltage Hot Swap™ controller with I2C compatible monitoring in a 200W, 36 to 72V application. Included on board is an input clamp and snubber, input and output voltage dividers for UV, OV, and PWRGD, LEDs to indicate the presence of various voltages and signals, high voltage layout rules and turret terminals for critical signals to facilitate evaluation in a working system. A distinct line of demarcation runs the length of the board, separating high voltage +48V referred potentials from ground. Input and output connections are made by 93 mil turrets which if removed, accommodate insertion of up to 12 gauge wires for in-situ testing. An I2C port designed to interface with DC590A allows control of DC786A with LTC's Quick Eval software. Design files for this circuit board are available. Call the LTC factory.
