Productoverzicht

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.
  • Critical conduction mode
  • Peak-current mode control
  • Skip-cycle mode for low-standby power
  • Hiccup mode for continuous overload protection
  • Cycle-by-cycle overcurrent protection maintains
  • Accuracy over the universal AC line
  • Line-voltage feed forward
  • OVP Protection by sensing the auxiliary winding
  • Direct opto-coupler interface
  • Leading edge blanking of current sense signal
  • Programmable soft-start
  • Thermal shutdown
  • Green product and no Sb/Br
Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
