ISL6553 Product details

The ISL6553 multi-phase PWM control IC together with its companion gate drivers, the HIP6601, HIP6602 or HIP6603 provides a precision voltage regulation system for advanced microprocessors. Multi-phase power conversion is a marked departure from earlier single phase converter configurations previously employed to satisfy the ever increasing current demands of modern microprocessors. Multi-phase converters, by distributing the power and load current results in smaller and lower cost transistors with fewer input and output capacitors. 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 two phase converter operating at 350kHz will have a ripple frequency of 700kHz. Moreover, greater converter bandwidth of this design results in faster response to load transients.

Features
