Note: 1.When Remote On/Off pin is open, for active low option, unit is off; for active high option, unit is on. 2.The efficiency is measured at normal Vin, full load and Ta=25°C.

  1. The total voltage increased by trim and remote sense should not exceed 15%Vo.
  2. Over Voltage Protection is specified at Vin=48V, full load and Ta=25°C, in hiccup mode.
