Notes
Unless otherwise noted, all specications are at nominal input voltage, nominal output voltage
and full load. General conditions are +25 Celsius ambient temperature, near sea level altitude,
natural convection airow. All models are tested and specied with external parallel 1 μF and 10 μF
multi-layer ceramic output capacitors. No external input capacitors are installed. All capacitors are
low-ESR types wired close to the converter. These capacitors are necessary for our test equipment
and may not be needed in the user’s application.
The module will operate when input voltage is within the 36-75V Operating Voltage Range, Output
regulation at full load will be achieved only when Vin >= 39V
Input (back) ripple current is tested and specied over 5 Hz to 20 MHz bandwidth. Input ltering is
Cbus = 0 μF, Cin = 100 μF and Lbus = < 4.7 μH.
The Remote On/Off Control is referred to -Vin.
Over-current protection is non-latching with auto reovery (Hiccup)
Regulation specications describe the output voltage changes as the line voltage or load current is
varied from its nominal or midpoint value to either extreme.
Output Ripple & Noise is measured with 750 μF capacitance, 10% ceramic and 90% OSCON. 20
MHz bandwidth.
