Toote ülevaade

The LM5023-2NBEVM evaluation module (EVM) is a fully assembled and tested circuit for evaluating the LM5023 device. The LM5023 is a AC to DC quasi resonant pulse width modulated (PWM) controller which contains all of the features needed to implement a highly efficient off line power supply. The LM5023 uses the transformer auxiliary winding for demagnetization detection to ensure critical conduction mode (CCM) operation. It features a hiccup mode for over current protection with an auto restart to reduce the stress on the power components during an overload. A skip cycle mode which reduces power consumption at light loads for energy conservation applications (ENERGY STAR, CEPCP, etc. ). The LM5023 also uses the transformer auxiliary winding for output overvoltage (OVP) protection, if an OVP fault is detected the LM5023 latches off the controller.
  • Standby power of less than 30mW
  • Output voltage regulation of less than 1%
  • Efficiency greater than 88%
  • Critical conduction mode
  • Peak current mode control mode
  • Skip cycle mode for low standby power
  • Line current feed forward
  • Maximum frequency clamp of 130KHz
  • Direct optocoupler interface
  • Leading edge blanking of current sense auxiliary winding for demagnetization detection to signal
