ISL6262CRZ

Product Summary

The ISL6262CRZ is a two-phase buck converter regulator implementing Intel IMVP-6+ protocol with embedded gate drivers. The two-phase buck converter uses two interleaved channels to effectively double the output voltage ripple frequency, and thereby reduce output voltage ripple amplitude with fewer components; lower component cost; reduced power dissipation; and smaller real estate area. The heart of the ISL6262CRZ is the patented R3 Technology, Intersils Robust Ripple Regulator modulator. Compared with the traditional multiphase buck regulator, the R3 Technology has the fastest transient response. This is due to the R3 modulator commanding variable switching frequency during a load transient.
