SF1565SG - Highly Integrated Current Mode PWM Controller

Download the SF1565SG datasheet PDF. This datasheet also covers the SF1565 variant, as both devices belong to the same highly integrated current mode pwm controller family and are provided as variant models within a single manufacturer datasheet.

General Description

SF1565 is a high performance, highly integrated current mode PWM controller for medium to large offline flyback converter applications.

In SF1565, the PWM switching is internally trimmed to tight range.

Key Features

  • Built-in Soft Start Function.
  • Very Low Startup Current.
  • Frequency Reduction and Burst Mode Control for Energy Saving.
  • Built-in Frequency Shuffling.
  • Programmable Switching Frequency.
  • Built-in Synchronous Slope Compensation.
  • Cycle-by-Cycle Current Limiting.
  • Pins Floating Protection.
  • High Voltage CMOS Process with Excellent ESD Protection.
  • Current Mode Control.
  • Built-in Leading Edge Blanking (LEB).
  • Constant Power Limiting.
  • Audio Nois.
