TFS7706H

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
