Intersil HIP6303
The HIP6303 multi-phase PWM control IC together with its companion gate drivers, the HIP6601, HIP6602 or HIP6603 and Intersil MOSFETs provides a precision voltage regulation system for advanced microprocessors. These reductions accrue from the higher effective conversion frequency with higher frequency ripple current due to the phase interleaving process of this topology. For example, a three channel converter operating at 350kHz will have a ripple frequency of 1.05MHz.| Part No. | HIP6303 |
