Turn on Time Efficiency Cooling Standby Power 12 V/0.66 A < 200 ms Above 85% 050 C Open Frame < 50 mW Full Load in Still Air 230 Vac Description Key Features This user manual provides elementary information about an isolated Integrated Rugged 800 V Super Junction flyback with FSL518APG, it performs high efficiency and smaller MOSFET with SENSEFET Technology than 50mW no load power consumption. FSL518APG is an Builtin HV Current Source for Startup integrated pulse width modulation (PWM) and 800 V power switch with SENSEFET , it can help to save external MOSFET and sense PeakCurrentMode Control with Slope resistor, increase power density and reliability. This application is Compensation targeting auxiliary power supply for white goods and industrial Line Compensation for Maximum equipment, such as refrigerator, Emetering or similar types of OverPower Limiting equipment. Advanced Softstart for Low Electrical The PWM controller includes an integrated variable frequency Stress oscillator, UnderVoltage Lockout (UVLO), Leading Edge Blanking PeakCurrentMode Control with Builtin (LEB), optimized gate driver, internal softstart, and temperature Slope Compensation compensated precise current source for loop compensation and Pulsebypulse Current Limit self protection circuitry. This design focuses mainly on the FSL518APG current mode PWM controller. Please refer to Line Brownin, Brownout, FSL518APGs materials to get more information about this device. and OverVoltage Protection (LOVP) The FSL518APG is a current mode PWM controller, it can have Adjustable Burstmode Operation better response to handle dynamic operation. Controller combines line Frequency Hopping for Better EMI detection and burstmode adjustment in one pin. Its easy to achieve Various Protections: these functionalities just need voltage divider and one Zener diode. Auto Restart Mode: Brownout, OLP, Line detection includes brown in, brown out and line OVP, OVP, AOCP and TSD burstmode adjustment is for fine tune audible noise and light load Recovery Immediately by Triggering efficiency. Of course, it also provides frequency reduction with Level: LOVP loading decreasing for gaining more design margin to improve light load efficiency.
