NTE7154中文资料NTE数据手册PDF规格书

Description:

The NTE7154 is an integrated circuit in an 8–Lead DIP type package which controls the MOS power transistor and performs all necessary regulation and monitoring functions in free running flyback converters. Since good load regulation over a wide load range is attained, this device is particularly suitable for consumer as well as industrial power supplies.

Features:

● Fold–Back Characteristic Provides Overload Protection for External Diodes

● Burst Operation Under Short–Circuit and No Load Conditions

● Loop Error Protection

● Switch–Off In Case of Too Low Line Voltage (Under Voltage Switch–Off)

● Line Voltage Compensation of Overload Point

● Soft–Start for Smooth Start–Up

● Chip Over–Temperature Protection (Thermal Shutdown)

● On–Chip Parasitic Transformer Oscillation Suppression Circuitry

● Decrease of Regulated Voltage for Low Power Consumption
