Description
SF1565 Highly Integrated Current Mode PWM Controller .
SF1565 is a high performance, highly integrated current mode PWM controller for medium to large offline flyback converter applications.
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
* Pin
Applications
* In SF1565, the PWM switching is internally trimmed to tight range. To improve EMI performance, the IC integrates frequency shuffling function to reduce conduction EMI emission of a power supply. The IC also integrates Constant Power Limiting block to achieve constant output power limit from 90VAC t
