Description (continued)

diodes during the start-up sequence. Various protections such as

overvoltage, overload, overcurrent, maximum on-time protections

and avalanche-energy-guaranteed MOSFET secure good system-

level reliability.

Applications include the following:

▪ Set Top Box

▪ LCD PC monitor, LCD TV

▪ Printer, Scanner

▪ SMPS power supplies

Absolute Maximum Ratings at TA = 25°C
