General Description

SF1530 is a high performance, low cost, highly integrated current mode PWM controller for offline flyback converter applications.

PWM switching frequency with shuffling is externally programmable, which can reduce conduction EMI emission of a power supply.

When the output power demands decrease, the IC automatically decreases switching frequency for high power conversion efficiency.

Key Features

  • Proprietary “Zero OCP/OPP Recovery Gap” Control.
  • Built-in Soft Start Function.
  • All Pins Floating Protection.
  • Very Low Startup Current.
  • High Voltage CMOS Process with Excellent ESD Protection.
  • Frequency Reduction and Burst Mode Control for Energy Saving.
  • Current Mode Control.
  • Built-in Frequency Shuffling.
  • Programmable Switching Frequency.
  • Built-in Synchronous Slope Compensation.
  • Cycle-by-Cycle Current Limiting.
  • Built-in Leading Edge Bla.
