Combined Two-Switch Forward and Flyback Power Supply Controllers
Description
TFS7701-7708 HiperTFS™-2 Family
Combined Two-Switch Forward and Flyback Power Supply Controllers with Integrated High-Voltage MOSFETs
Product Enhancements
• Selectable 132 kHz main switching frequency for lower cost
and smaller magnetics
• Increased main peak power vs.
HiperTFS-1
• Self-biased high-side driver eliminates high-side bias winding
and diode
