Notes
➀
Unless otherwise noted, all specifications are at nominal input voltage, nominal output voltage
and full load. General conditions are +25˚ Celsius ambient temperature, near sea level altitude,
natural convection airflow. All models are tested and specified 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.
➁
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
➂
Input (back) ripple current is tested and specified over 5 Hz to 20 MHz bandwidth. Input filtering is
Cbus = 0 µF, Cin = 100 µF and Lbus = < 4.7 µH.
➃
The Remote On/Off Control is referred to -Vin.
➄
Over-current protection is non-latching with auto reovery (Hiccup)
➅
Regulation specifications describe the output voltage changes as the line voltage or load current is
varied from its nominal or midpoint value to either extreme.
➆
Output Ripple & Noise is measured with 750 µF capacitance, 10% ceramic and 90% OSCON. 20
