Figure U: Measurement of Ic with Vcc. Il = 12.5Amps,
Cout = 220 µF, Vin = 48 VDC.
Figure V: Measurement of Is with Vcc Il = 12.5 Amps,
Cout=220 µF, Vin=48 VDC.
Back-Feed Capability
The HBA is not a synchronous rectifier power
converter.
does not have the capability to sink current into the
output pins. Therefore, back feed capability is not a
concern.
It uses traditional diode rectifiers and
