The LTC4223 includes an internal pass FET for the 3.3Vauxiliary supply and a driver for an external N-channelpass FET for the 12V payload supply. Inrush current forboth supplies is controlled: the auxiliary supply has afi xed 240mA active current limit and the 12V ramp rateis controlled by an external capacitor. A timed circuitbreaker and fast current limit protect both supplies againstsevere overcurrent faults. It also features an adjustableanalog current limit with a circuit breaker timeout forthe 12V supply.
