Pin Function
+12V Supply Power [A/B]: Pin 5 is the input to the drain side of the internal
MOSFET switch for +12V Slot A. Pin 32 is the input to the drain side of the
internal MOSFET switch for +12V Slot B. These two pins must ultimately
connect to each other within 10cm of the MIC2593. An undervoltage lockout
circuit (UVLO) prevents the switches from turning on while this input is less than
its lockout threshold.
+12V Output [A/B]: Pin 10 is connected to the source terminal of the internal
MOSFET switch for +12V Slot A and pin 27 is connected similarly for Slot B.
–12V Supply Power [A/B]: Pin 17 is the input to the drain side of the internal
MOSFET switch for +12V Slot A. Pin 18 is the input to the drain side of the
internal MOSFET switch for –12V Slot B. These two pins must ultimately
connect to each other within 10cm of the MIC2593. An undervoltage lockout
circuit (UVLO) prevents the switches from turning on while this input is less than
its lockout threshold.
–12V Output [A/B]: Pin 19 is connected to the source terminal of the internal
MOSFET switch for –12V Slot A and pin 20 is connected similarly for Slot B.
12V Slew Rate Control [A/B]: Connect capacitors between these pins and
ground to set the output slew rates of the +12V and –12V supplies. See the
“Functional Description” section for more details.
