Single Package Design |
IR has leveraged it’s world class packaging technology developed for the DirectFET®, improving the thermal capability and layout of the PowIRstage® significantly over that of other MCM packages. |

|
|
Other MOSFET layout implementations use a multi-chip, side-by-side arrangement of the high and low side MOSFETs and driver IC, taking up significant board real estate and creating more electrical leakage. |

Cooler temps. = Higher Overclocks |
Overheat |
Not enough power
for overclocking |
IR3550 PowIRstage® ICs remain cooler than other MOSFET designs, allowing users to overclock to greater levels of performance. Each power component has a maximum thermal operational temperature, and once it is reached, adding more voltage will only result in a failed overclock. Since IR3550 PowIRstages® are able to operate at cooler temperatures at higher voltages than traditional designs, overclockers are able to have more headroom to increase voltages, resulting in higher potential overclocks. |
