CRT driver National Semiconductor

•Requires few external components
•Family of standard inductors and transformers
•NPN output switches 3.0A, can stand off 65V
•Wide input voltage range: 4V to 40V
•Adjustable switching frequency: 100 kHz to 200 kHz
•External shutdown capability
•Draws less than 60 µA when shut down
•Frequency synchronization
•Current-mode operation for improved transient response, line regulation, and current limit
•Internal soft-start function reduces in-rush current during start-up
•Output transistor protected by current limit, under voltage lockout, and thermal shutdown
•System output voltage tolerance of ±4% max over line and load conditions
