DC786A

DC786A demonstration circuit showcases the LTC®4260CGN 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. Typical applications include servers, routers, switches, mass storage, central office computing, fan trays.

• Configured for 200W, 36 to 72V
• Provision for short pin control of turn-on
• 12C monitoring of load current, input and output voltage
• 12C control of device features and reporting of device status
• Provision for on-board input and output bypassing
• High voltage layout enforces 60mil minimum spacing
• LEDs indicate +48V input, +48V/5A output, power bad, alert status and 12C port logic states
• Input clamping included on-board
