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 .
PDIP−7
(PDIP−8 LESS PIN 6)
PDIP−7 GULLWING
(PDIP−7 GW)
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.
