Product Overview

The LM5021MM-1/NOPB is an off-line Pulse Width Modulation (PWM) Controller contains all of the features needed to implement highly efficient off-line single-ended flyback and forward power converters using current-mode control. It features include an ultra-low (25µA) start-up current, which minimizes power losses in the high voltage start-up network. A skip cycle mode reduces power consumption with light loads for energy conserving applications (ENERGY STAR®, CECP and so forth). Additional features include under-voltage lockout, cycle-by-cycle current limit, hiccup mode overload protection, slope compensation, soft-start and oscillator synchronization capability. This high performance 8-pin IC has total propagation delays less than 100ns and a 1MHz capable oscillator that is programmed with a single resistor.
  • Current mode control
  • Skip cycle mode for low standby power
  • Single resistor programmable oscillator
  • Synchronizable oscillator
  • Adjustable soft-start
  • Direct opto-coupler interface
  • Under voltage lockout (UVLO) with hysteresis
  • Cycle-by-cycle over-current protection
  • Hiccup mode for continuous overload protection
  • Leading edge blanking of current sense signal
  • 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.
