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
