standby mode is desired. Overall power consumption can be reduced by allowing the

microcontroller to enter a low power mode and shut down PFC operation without having

to reboot the microcontroller. Since the R-C combination cannot provide enough power

to sustain microcontroller operation, the microcontroller must stay active running the

PFC section to power itself.

IXYS IXTP3N50P

PolarHVTM N-

Channel Power

MOSFET

The IXTP3N50P is a 3A 500V general purpose power MOSFET that comes

from the family of IXYS PolarHV MOSFETs. When comparing equivalent die

sizes, PolarHT results in 50% lower RDS(ON), 40% lower RTHJC (thermal resis-

tance, junction to case), and 30% lower Qg (gate charge) enabling a 30% - 40%

die shrink, with the same or better performance verses the 1st generation power

MOSFETs.

Within the ballast demonstrator itself the IXTP3N50 serves two functions. The first of

which is the power switching pair of devices in the half-bridge circuit that drives the

lamps. While a third device serves in the main PFC circuit as the power switch that

drives the PFC inductor.
