Quality Control: Learn More
The onsemi NCP1249AD65R2G is an offline switching controller designed for flyback topologies. This component operates at a 65kHz switching frequency and features a 10-SOP (0.154", 3.90mm Width) package with 9 leads, suitable for surface mounting. With a maximum duty cycle of 80%, it offers robust fault protection including over load, over power, over temperature, over voltage, and short circuit conditions. The device requires an 18V start-up voltage and operates from a Vcc/Vdd range of 10V to 30V. This isolated flyback controller is commonly utilized in power supply applications for consumer electronics, industrial automation, and lighting systems.
