APPLICATIONS
a73 FOUR LAMP ELECTRONIC BALLAST FOR:
120 V MAINS IN PUSH-PULL
CONFIGURATION;
277 V MAINS IN HALF BRIDGE CURRENT
FEED CONFIGURATION.
DESCRIPTION
The device is manufactured using high voltage
Multi Epitaxial Planar technology for high
switching speeds and high voltage capability. It
uses a Cellular Emitter structure with planar edge
termination to enhance switching speeds while
maintaining a wide RBSOA.
Thanks to an increased intermediate layer, it has
an intrinsic ruggedness which enables the
transistor to withstand a high collector current
level during Breakdown condition, without using
the transil protection usually necessary in typical
converters for lamp ballast.
