LM3842A - CURRENT MODE PWM CONTROLLER

General Description

The LM384xA are fixed frequency current-mode PWM controller.

They are specially designed for Off-Line and DC-to-DC converter applications with minimal external components.

Key Features

  • Automatic feed forward compensation.
  • Optimized for offline converter.
  • Double pulse suppression.
  • Current mode operation to 500kHz.
  • High gain totem pole output.
  • Internally trimmed bandgap reference.
  • Undervoltage lockout with hysteresis.
  • Low start up current: < 0.3mA.
  • Moisture Sensitivity Level 3 LM3842A/3A/4A/5A SOP-8 PKG DIP-8 PKG.
