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
• Package lead form and pinout modified for easier insertion and
PC-board layout
• Tighter UV(ON) standby threshold tolerance
• Improved standby no-load performance
Key Benefits
• Single IC solution for two-switch forward main (66 kHz/132 kHz)
and flyback (132 kHz) standby
• High integration allows smaller form factor and higher power
density designs, with reduced component count
• Incorporates control, gate drivers, and three power MOSFETs
• Level shift technology eliminates need for pulse transformer
• Protection features include: UV, OV, OTP, OVP, standby OPC,
SCP, and ILIMIT
• Transformer reset control, prevents saturation under all conditions
• Main duty cycle operation above 50% for reduced rms currents
and lower output diode voltage rating
• Less than 10% variation in standby overload power over input
voltage range
• Up to 586 W peak output power in a highly compact package
• >90% efficiency at full load
• Simple clip mounting to heat sink without need for insulation pad
• Halogen free and RoHS compliant
Typical Applications
• PC (80 PLUS® Bronze and 80 PLUS Silver)
• Printer
• LCD TV
• Video game consoles
• High-power adapters
• Industrial and appliance
