onsemi NCP11187A100PG

NCP1118x integrates a peak current mode PWM controller employing mWSaver technology and a highly robust 800 V SJ MOSFET providing especially enhanced performance in flyback converters. The mWSaver technology reduces switching frequency and operating current of the controller at light−load condition, which helps avoid acoustic−noise problems and even meet international power conservation standards, such as Energy Star. Additionally, NCP1118x includes a high−voltage startup circuit, frequency−hopping function, slope compensation, constant output power limit, and highly reliable and various protections, which allows easy design, less BOM counts, smaller PCB size and designing cost−effective off−line power supply. The protections feature a protection of a feedback pin open−loop, current−sense resistor short, brown−out and line over−voltage using an line voltage sensing pin, which operate with auto−recovery operation.
