onsemi Effektswitch IC 1, 7 Ben Hög sida Hög sida NCP11187 PDIP-7

The ON Semiconductor NCP11187A100PG 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. The device comes in a PDIP-7 package and, 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 device has an integrated 800 V super junction MOSFET
