FAN6793 - Dual-PWM Combination Controller

Download the FAN6793 datasheet PDF. This datasheet also covers the FAN6791 variant, as both devices belong to the same dual-pwm combination controller family and are provided as variant models within a single manufacturer datasheet.

Description

The highly integrated FAN6791/3 dual PWM combination controller provides several

Features

  • High-Voltage Startup.
  • Low Operating Current.
  • Interleaved Stand-by PWM / Forward PWM Switching.
  • Green Mode Stand-by PWM / Forward PWM.
  • Linearly Decreasing Stand-by PWM Frequency to 20kHz.
  • Remote On / Off.
  • AC Brownout Protection.
  • Forward PWM with Soft-Start.
  • Frequency Hopping to Reduce EMI Emissions.
  • Cycle-by-Cycle Current Limiting for Stand-by PWM / Forward PWM.
  • Leading-Edge Blanking for Stand-by PWM / Forward PWM.
  • Synchronized Slope Co.
