LM5023MM-2/NOPB

TEXAS INSTRUMENTS  LM5023MM-2/NOPB  控制器, 电流模式控制器, PWM, 14V-8V电源, 130 kHz, VSSOP-8

The 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.
