SYSTEM FEATURES
Peak efficiency Vin = 390 VDC, Iout= 10 A 94.5%
Efficiency Vin = 370 VDC to 410 VDC, 4.2 A <Iout < 42.5 A > 90%
Full-load efficiency Vin = 370 VDC, Iout = 42.5 A 92%
Resonant frequency 250 kHz
Switching frequency 200 350 kHz
These default overcurrent limits are programmable and may be adjusted to allow high-load operation under noisy test conditions or to limit these currents to lower levels.
Note that the resonant tank inductors are the hottest components on the board. Use an external air cooling fan (CFM rating > 50) directed at the board when operating with loads (Iout) of 30 A or higher.
