DC1354B-B

DC1354B-B is a demonstration circuit for positive high voltage hot swap controller featuring the LT1641-1, LT1641-2, LT4256-1 or LT4256-2. The board facilitates measurement of transient conditions, steady state operation with different loads, and fault conditions. The controller responds to fault conditions such as input undervoltage (UV), output power good (PWRGD) fault, and overcurrent and response can be verified by the output voltage (VOUT) LED state and PWRGD pin signal. The LT1641-1 and LT4256-1 latch off if MOSFET shuts off under overcurrent condition, while LT1641-2 and LT4256-2 automatically restart after time-out delay.
