TFS757-764HG HiperTFS™ Family
Combined Two-Switch Forward and Flyback Power Supply Controllers with Integrated High
Voltage MOSFETs
Key Benefits Single chip solution for two-switch forward main and flyback
standby High integration allows smaller form factor and higher power
density designs Incorporates control, gate drivers, and three power
MOSFETS Level shift technology eliminates need for pulse transformer Protection features include: UV, OV, OTP, OCP, and SCP Transformer reset control Prevents transformer saturation under all conditions Allows >50% duty cycle operation Reduces primary side RMS currents and conduction losses Standby supply provides built-in overload power compensation Up to 434 W total output power in a highly compact package Up to 550 W peak High efficiency solution easily enables design to meet
stringent efficiency specifications >90% efficiency at full load No-load regulation and low losses at light-load Simple clip mounting to heat sink without need for insulation pad Halogen free and RoHS compliant
Applications PC Printer LCD TV Video game consoles High-power adapters Industrial and appliance high-power adapters
