Description

The HiperTFS-2 devices incorporate a high-power two-switch-forward converter and a mid-power flyback (standby) converter into a single, low-profile eSIP™ power package. The single chip solution provides the controllers for the two-switch-forward and flyback converters, high- and low-side drivers, all three of the high-voltage power MOSFETs, and eliminates the converter’s need for costly external pulse transformers. The device is ideal for high power applications that require both a main power converter (two-switch forward) up to 586 W peak, and a standby converter (flyback) up to 20 W. The devices operate over a wide input voltage range, and can be used following a power-factor correction stage such as HiperPFS.

 

New with HiperTFS-2

  • Improved assembly flow – changed from 3 row package to 2 row package
  • Up to 40% more peak power – easily meeting the next generation Intel CPU peak power requirement
  • Self biased high-side driver – eliminating bias winding
  • Main convertor now offers 66kHz/132kHz options

 

Product Highlights

Key Benefits

  • Single chip solution for two-switch forward main and flyback 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
