DC1162A-A

DC1162A-A demonstration circuit board allows easy evaluation of the performance of the LTC4223-1 dual hot swap controller for Advanced Mezzanine (AMC) Cards. This controller is designed for applications in equipment satisfying the Micro Telecommunications Computing Architecture Specification requirements (+12V main rail with load capability up to 9A and +3.3V auxiliary rail with 150mA load capability). DC1162A includes two printed circuit boards: A simulated carrier board with the LTC4223, 170-pin AMC connector, passive components, and turrets for both rails. The second board is a simulated AMC mezzanine card, with the same +12V and +3.3V rail outputs as the carrier board. This board also has a typical amount of bypass capacitance onboard and more may be added externally.

• Undervoltage lockout on both rails and Vcc
• Integrated 0.3ohm AUX MOSFET
• Fast (less than 1us) peak fault current limit
• Circuit breaker function on both rails
• Adjustable main rail current limit
• Main rail load current monitoring
• Gate drive for external N-channel MOSFET
• Adjustable response time for overcurrent protection
• Adjustable supply voltage power-up rate
• Thermal shutdown protection, latch off after fault
