Power integrated circuits designed for tight form factors offered by Power Integrations
SAN JOSE, Calif., 28 Nov. 2013. Power Integrations in San Jose, Calif., is introducing the HiperTFS-2 family of power integrated circuits, combining two-switch-forward and flyback power-supply controller ICs with integrated high-voltage MOSFETs.
This level of integration in these power ICs saves more than 20 components, resulting in a small form factor and high power density. The main converter provides a selectable switching frequency between 66 kHz and 132 kHz, which reduces system cost by enabling the use of small magnetics.
HiperTFS-2 integrated circuits enable efficiencies of more than 90 percent at full load. They also provide 175 percent peak power, a requirement of next-gen Intel CPUs.
This single-chip implementation of a two-switch-forward main (66/132 kHz) and flyback (132 kHz) standby power supply delivers to 364 Watts total output power (586 Watts peak) in a compact, two-row eSIP power package.
Safety features include undervoltage, overvoltage, over-temperature, overcurrent, and short-circuit protection. A transformer-reset control function prevents saturation.
