APPLICATIONS
FOUR LAMP ELECTRONIC BALLAST FOR: 120 V MAINS IN PUSH-PULL CONFIGURATION; 277 V MAINS IN HALF BRIDGE CURRENT FEED CONFIGURATION. s SWITCH MODE POWER SUPPLIES s 3 1 2 TO-220 DESCRIPTION
Thanks to an increased intermediate layer, it has an intrinsic ruggedness which enables the transistor to withstand an high collector current level during breakdown condition, without using the transil protection usually necessary in typical converters for lamp ballast.
