AV3842B - (AV3842B / AV3843B) LINEAR INTEGRATED CIRCUIT

General Description

The @vic AV3842B/3843B are specifically designed for Off-Line and dc-to-dc converter applications offering the designer a cost-effective solution with minimal external components.

The AV3842B has UVLO thresholds 16V (on) and 10V(off), ideally suited for off-line converters.

Key Features

  • Trimmed Oscillator for Precise Frequency Control.
  • Oscillator Frequency Guaranteed at 250kHz.
  • Current Mode Operation to 500kHz.
  • Automatic Feed Forward Compensation.
  • Latching PWM for Cycle-By-Cycle Current Limiting.
  • Internally Trimmed Reference with Undervoltage Lockout.
  • High Current Totem Pole Output.
  • Undervoltage Lockout with Hysteresis.
  • Low Startup and Operating Current DIP-8 BLOCK.
