Notes:
– Keep load currents < 100mA on ±48V channels and < 250mA on ±12V channels.
– Output voltages can be margined by ±10% from nominal with the default resistor values. These values can be eas-
ily changed. See section Changing Nominal Output Voltages. Use the LTC2975 Resistor Selection Tool which is
accessed from LTpowerPlay.
