High frequency ics slash system cost and board space

The devices combine two switch forward and flyback power supply controller ics with integrated high voltage mosfets, which the company claims reduces board space and increases power density. The main converter provides a selectable switching frequency between 66 and 132kHz, lowering system cost by enabling the use of very small magnetics. The devices are said to enable effiencies of up to 90% e at full load. They also provide 175% peak power, a requirement of next gen Intel cpus. This single chip implementation of a two switch forward main (66/132kHz) and flyback (132kHz) standby power supply delivers up to 364W total output power (586W peak) in a compact, two row eSIP power package. Safety features include under voltage, over voltage, over temperature, over current and short circuit protection. A transformer reset control function prevents saturation under all conditions.
