AN829 APPLICATION NOTE
– Can be mounted on the same heatsink as the ISOTOP
– intrinsic diode for controller input protection
– very low parasitic inductance improving signal/noise ratio.
However, the peak current limitation will be affected by the MOSFET thermal characteristic.
DESIGN RULE EXAMPLE
Taking the following operating conditions (see figure 2):
Vin rms = 230Vac +10% -15% (f=50Hz)
Iin rms = 16Arms
Pout = 3000W
Vout = 400Vdc
or
Vin rms = 120Vac +20% -20% (f=60Hz)
Iin rms = 15Arms
Pout = 1400W
Vout = 400Vdc
