LM5023MM-2/NOPB

ШИМ контроллер токового режима, 14В-8В питание, 130кГц, VSSOP-8.

The LM5023MM-2/NOPB is a quasi-resonant Pulse Width Modulated (PWM) Controller contains all of the features needed to implement a highly efficient off-line power supply. It uses the transformer auxiliary winding for demagnetization detection to ensure critical conduction mode (CrCM) operation. It features a hiccup mode for overcurrent protection with an auto restart to reduce the stress on the power components during an overload. A skip-cycle mode reduces power consumption at light loads for energy conservation applications (ENERGY STAR®, CEPCP and so forth). It also uses the transformer auxiliary winding for output overvoltage protection (OVP); if an OVP fault is detected the LM5023 latches off the controller.
